  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

  In the present embodiment, a case will be described as an example in which CAE for verifying performance by technical calculation using a computer is performed when performing a collision simulation in vehicle type development of an automobile. In the present embodiment, the batch processing system performs a process of creating mesh data serving as CAE input data from CAD data of each of a plurality of parts constituting an automobile by batch processing. Thereby, the CAE model creation period can be significantly shortened.

FIG. 1 is a block diagram showing a configuration of a batch processing system 10 in the present embodiment.
The batch processing system 10 includes a batch processing unit 100, a mesh data creation processing unit 200, a parts list storage unit 220, a mesh data creation condition storage unit 230, a CAD data storage unit 240, a part type data storage unit 242, an offset / neutral surface. A data storage unit 244, a mesh data storage unit 246, and a corrected mesh data storage unit 248 are included.

  The mesh data creation processing unit 200 creates mesh data for CAE analysis (numerical simulation) from CAD data (structure information). The mesh data creation processing unit 200 includes a CAD data acquisition unit 202, a component type coordinate conversion unit 204, an offset / neutral surface data creation unit 206, a mesh data creation unit 208, and a mesh data modification unit 210.

  The batch processing unit 100 performs control for causing the mesh data creation processing unit 200 to perform the above-described processing in batch processing. The batch processing unit 100 includes a batch processing instruction unit 102, a task status management unit 104, an error handling processing unit 106, an error handling procedure setting storage unit 120, and a task status storage unit 122.

  The mesh data creation condition storage unit 230 stores mesh data creation conditions. Although not shown, in the present embodiment, the mesh data creation condition storage unit 230 has an appropriate parameter file for storing parameters when the mesh data creation processing unit 200 creates mesh data, and the created mesh data is appropriate. And a criteria file for storing reference data for determining whether or not. Parameters such as mesh size and angle are stored in the parameter file as mesh data creation conditions. The criteria file stores ideal values, good values, warning values, fail values, etc. of the mesh size and angle. Each parameter file has a criteria file with the same name. Further, the mesh data creation condition storage unit 230 can include a plurality of parameter files and corresponding criteria files.

  The parts list storage unit 220 stores a parts list, which is a list of information relating to automobile components that are analysis objects. FIG. 2 is a diagram illustrating an example of a parts list stored in the parts list storage unit 220. Here, the parts list includes a level field, a part name field, a collector name field, a type field, a product name field, a product number field, a plate thickness field, a material field, a mesh condition file name field, and an arrangement matrix field.

  In the level column of the hierarchy, the hierarchy level of the CAD data of each component is stored. The part name column stores the same name as the CAD data file name of each corresponding component stored in a CAD data database (not shown) storing CAD data of various parts. Thereby, based on the part name described in the parts list, corresponding CAD data can be acquired using the part name as a key. In the type column, for example, data types of each component such as spots (welding points), bolts / nuts, parts, and the like are stored. When the component is a part having a curved surface, the plate thickness of the component is stored in the plate thickness column. Similarly, in the case where the component is a part having a curved surface, a parameter file for storing creation conditions for generating mesh data of the component and a file name of the criteria file are stored in the mesh condition file name column.

  In the collector name column, a name unique to each component in the automobile is stored. For example, when two identical parts are included in an automobile that is an analysis object, these parts are given the same part name but different collector names. In the arrangement matrix column, arrangement information for converting the coordinates of the CAD data of each component into the vehicle body coordinates in the automobile is stored. Although not shown here, the arrangement matrix column can include a translation matrix for translation and a transformation matrix for rotation.

  Returning to FIG. 1, the batch processing instruction unit 102 of the batch processing unit 100 instructs the mesh data creation processing unit 200 to perform batch processing for sequentially performing processes for creating mesh data. The task status management unit (error detection unit) 104 monitors the status of processing by the mesh data creation processing unit 200 and manages the status of each task. The task status management unit 104 records, in the task status storage unit 122, information indicating that each process has been completed or information indicating that an error has occurred for each component. The task status management unit 104 detects the type of error when an error occurs in any of the processes of the mesh data creation processing unit 200.

  The error handling procedure setting storage unit 120 stores a type of error that may occur in the mesh data creation processing unit 200 and a handling procedure for the error in association with each other. When the task status management unit 104 detects an error, the error handling processing unit 106 refers to the error handling procedure setting storage unit 120 based on the type of error detected by the task status management unit 104 and sets the error type. A corresponding processing instruction is output to the mesh data creation processing unit 200.

  The CAD data acquisition unit 202 of the mesh data creation processing unit 200 refers to the parts list in the parts list storage unit 220 and uses the part name as a key to identify the components included in the analysis target from the CAD data database (not shown). Download CAD data. The CAD data acquisition unit 202 stores the downloaded CAD data in the CAD data storage unit 240. The CAD data can be either a surface type in which the structure is expressed three-dimensionally by a curved surface or a solid type in which the structure is expressed three-dimensionally by a collection of surfaces. When the CAD data is a surface type, the CAD data can also include an arrow indicating the thickness direction.

  The component type division coordinate conversion unit 204 refers to the parts list in the parts list storage unit 220, and classifies the CAD data for each component stored in the CAD data storage unit 240 based on the “type” of the parts list by type. And processing for converting the data of each part into the vehicle body coordinate system based on the “placement matrix” of the parts list. The part type coordinate conversion unit 204 stores the processed data in the part type data storage unit 242. The component type data storage unit 242 includes a folder corresponding to each component type. Although not shown, in this embodiment, the component type data storage unit 242 includes a spot folder, a bolt / nut folder, and a parts folder. The part type coordinate conversion unit 204 stores the data of each part in a corresponding folder of the part type data storage unit 242.

  The offset / neutral plane data creating unit 206 is an offset plane or neutral plane data (hereinafter referred to as offset / neutral plane data) which is a curved surface at the center of the plate of the data stored in the parts folder of the part type data storage unit 242. ). The offset / neutral surface data creation unit 206 first determines whether the data read from the component type data storage unit 242 is a surface type or a solid type. When the data is a surface type, the offset / neutral surface data creation unit 206 creates offset surface data based on “plate thickness” with reference to the parts list in the parts list storage unit 220. Specifically, the offset / neutral surface data creation unit 206 creates offset surface data by offsetting the read data in the direction of the arrow to half the plate thickness (neutral surface). If the data is a solid type, the neutral plane data is created with the plate center as the neutral plane. The offset / neutral surface data creation unit 206 stores the created offset / neutral surface data in the offset / neutral surface data storage unit 244.

  The mesh data creation unit 208 creates grid points in the offset / neutral surface data stored in the offset / neutral surface data storage unit 244 and creates mesh data obtained by dividing the surface. The mesh data creation unit 208 reads out the corresponding parameter file from the mesh data creation condition storage unit 230 based on the “mesh condition file name” with reference to the parts list in the parts list storage unit 220. Subsequently, the mesh data creation unit 208 creates mesh data based on parameters such as the mesh size and angle of the read file. The mesh data creation unit 208 stores the created mesh data in the mesh data storage unit 246.

  The mesh data correction unit 210 determines whether the mesh data created by the mesh data creation unit 208 is appropriate. The mesh data correction unit 210 refers to the parts list in the parts list storage unit 220, refers to the criteria file in the mesh data creation condition storage unit 230 based on the “mesh condition file name”, and meshes that do not satisfy the condition and the number of meshes Is detected. Specifically, the mesh data correction unit 210 detects a mesh that deviates from the failure value of the criteria file. The mesh data correction unit 210 corrects the mesh data based on an instruction from the error handling processing unit 106 of the batch processing unit 100 and stores the corrected mesh data in the corrected mesh data storage unit 248. This process will be described later.

  The above-described processing of the CAD data acquisition unit 202, the component type coordinate conversion unit 204, the offset / neutral plane data generation unit 206, the mesh data generation unit 208, and the mesh data correction unit 210 is performed by the batch processing unit 100. This is performed based on an instruction from the processing instruction unit 102.

Next, processing when an error occurs in the processing of the mesh data creation processing unit 200 will be described.
FIG. 3 is a diagram illustrating an example of an internal configuration of the error handling procedure setting storage unit 120. The error handling procedure setting storage unit 120 includes a process column, an error code column, an error content column, and an error handling column.

  Here, an offset / neutral plane data creation process is shown as an example. For example, if the offset cannot be offset because the sheet thickness is not listed in the parts list, and offset / neutral plane data cannot be created, the error code is “104”. It is set to proceed to the creation process.

  Also, for example, if the plate thickness is listed in the parts list but cannot be offset and offset / neutral surface data cannot be created, create mesh data with the curved surface before offset with error code “105”. Thereafter, it is set that each mesh is offset with respect to mesh data. If the component has a complicated curved surface shape, the offset may not be successful. In such a case, offset / neutral surface data may be created by first creating mesh data and offsetting each mesh. Therefore, by making such settings, it is possible to create offset / neutral plane data even when offset cannot be performed by a normal procedure.

  For example, in the example shown in FIG. 3, when the task status management unit 104 detects an error code “104”, the error handling processing unit 106 refers to the error handling procedure setting storage unit 120, and generates a mesh data creation processing unit. At 200, an instruction to perform the process of the next mesh data creation process is output with the offset / neutral plane data creation process omitted.

  Further, for example, when the task status management unit 104 detects an error with the error code “105”, the error handling processing unit 106 refers to the error handling procedure setting storage unit 120 to the mesh data creation processing unit 200 for the offset / neutral surface. An instruction to perform the process of creating mesh data is output by omitting the data creation process. Further, the error handling processing unit 106 performs a process in which the mesh data creation unit 208 of the mesh data creation processing unit 200 creates mesh data in response to this instruction, and if no error is detected, the offset / neutral plane data An instruction to perform a step of generating offset / neutral surface data of each mesh for mesh data is output to the creation unit 206.

  Although not shown, the error handling unit 106 determines that an error has occurred in the mesh data creation process when the mesh data creation unit 208 cannot create mesh data, and sets the mesh creation conditions set in advance. Under the changed new conditions, the mesh data creation unit 208 is instructed to execute a process of creating mesh data.

  Similarly, even when the mesh data is created by the mesh data creation unit 208, the error handling processing unit 106, if the number of meshes deviating from the fail value detected by the mesh data modification unit 210 is equal to or greater than a predetermined number, It is determined that an error has occurred in the data creation process, and the mesh data correction unit 210 is instructed to execute the process of creating mesh data under new conditions obtained by changing preset mesh creation conditions. For example, the error handling processing unit 106 performs node movement, mesh subdivision, mesh combination, and the like on the mesh detected by the mesh data correction unit 210. Thereafter, meshes that do not satisfy the condition and the number of meshes are detected again, and when the number of meshes that do not satisfy the condition is decreased from the previous time, the process of adopting the new condition is repeated. The mesh data correction unit 210 stores the corrected mesh data in the corrected mesh data storage unit 248.

  FIG. 4 is a diagram illustrating an example of information stored in the task status storage unit 122 by the task status management unit 104. The task status storage unit 122 stores the status of each process in association with the collector name.

  For example, for the component with the collector name “1235”, “◯” is stored in the CAD data acquisition step, the component type coordinate conversion step, and the mesh data correction step. Here, “◯” indicates that the process was performed without an error. On the other hand, “◯ (105)” is stored in the offset / neutral plane data creation process and the mesh data creation process. This is because the error code “105” error occurs in the offset / neutral surface data creation process, and the mesh data creation process is performed after the offset / neutral surface data creation process is omitted. As shown, offset / neutral plane data of each mesh is created, and processing of these steps is performed without causing an error.

  Further, for example, for the part with the collector name “1236”, “104” is stored in the offset / neutral plane data creation step. This indicates that the error code “104” error occurred in the offset / neutral surface data creation process, and the mesh data creation process was performed without the offset / neutral surface data creation process.

  Next, a processing procedure of the batch processing system 10 will be described with reference to a flowchart. FIG. 5 is a flowchart showing a procedure for creating CAE analysis mesh data in the batch processing system 10 according to the present embodiment.

  In the present embodiment, a parts list of an analysis object is prepared in advance (S10). In this state, when the batch processing instruction unit 102 instructs the mesh data generation processing unit 200 to generate mesh data, first, the CAD data acquisition unit 202 refers to the parts list storage unit 220 and a CAD data database (not shown). The corresponding CAD data is downloaded from and stored in the CAD data storage unit 240 (S20). Subsequently, the component type classification coordinate conversion unit 204 refers to the parts list storage unit 220 and performs processing for classifying the CAD data for each component by type and processing for converting the data of each component into the vehicle body coordinate system. (S30).

  Thereafter, the batch processing instruction unit 102 targets the data stored in the parts folder of the part type data storage unit 242 as an object, the offset / neutral plane data generation unit 206, the mesh data generation unit 208, and the mesh data correction unit. 210 is instructed to perform processing for offset / neutral plane data creation, mesh data creation, and mesh data correction in this order for each part.

  The offset / neutral surface data creation unit 206 refers to the parts list storage unit 220 based on the instruction of the batch processing instruction unit 102, and offsets the corresponding data stored in the parts folder of the part type data storage unit 242. Neutral surface data is created and stored in the offset / neutral surface data storage unit 244 (S40). The mesh data creation unit 208 reads the corresponding creation conditions from the mesh data creation condition storage unit 230 with reference to the parts list storage unit 220 based on the instruction of the batch processing instruction unit 102, and the offset / neutral plane data storage unit The mesh data of the offset / neutral plane data stored in 244 is created. The mesh data creation unit 208 stores the created mesh data in the mesh data storage unit 246 (S50). Based on the instruction from the batch processing instruction unit 102, the mesh data correction unit 210 reads the corresponding reference data from the mesh data creation condition storage unit 230 with reference to the parts list storage unit 220, and is stored in the mesh data storage unit 246. The mesh that does not meet the criteria is detected from the mesh data. The mesh data correction unit 210 appropriately corrects the mesh data based on an instruction from the error handling processing unit 106. The mesh data correction unit 210 stores the corrected mesh data in the corrected mesh data storage unit 248 (S60). The mesh data stored in the corrected mesh data storage unit 248 is used as input data for CAE analysis.

FIG. 6 is a flowchart showing a processing procedure of the batch processing unit 100.
When the batch processing instruction unit 102 instructs the mesh data creation processing unit 200 to perform any process for any part (S100), the task status management unit 104 monitors whether or not an error has occurred in the processing. (S102). The batch processing instruction unit 102 can instruct the mesh data creation processing unit 200 to collectively process a plurality of processes and a plurality of parts. In this case, the task status management unit 104 monitors each process for each component.

  If no error occurs (NO in S102) and the process ends normally (YES in S104), the task status management unit 104 records the completion of the processing in the task status storage unit 122 (S106). If there is a next process (YES in S108), the task status management unit 104 proceeds to monitor the next process (S110). In step S108, if there is no next process (NO in S108), it is determined whether there is a next part (S112). If there is a next part, the process proceeds to the next part (S114). The process from step S102 is repeated. If there is no next part in step S112 (NO in S112), the process ends.

  On the other hand, if an error is detected in step S102 before normal completion in step S104 (YES in S102), the task status management unit 104 records an error code in the task status storage unit 122 (S120). Thereafter, it is determined whether or not the process is to be ended (S122). If the process is not to be ended (NO in S122), the error handling processing unit 106 refers to the task status storage unit 122 and gives an instruction for processing according to the procedure. The data creation processing unit 200 is performed (S124). The task status management unit 104 also monitors the process, and if an error does not occur (NO in S126) and completes normally (YES in S128), the task status storage unit 122 records the completion of the process in the task status storage unit 122 ( S130). If there is a next process at the time of error (YES in S132), the process returns to step S124, and the task status management unit 104 also monitors the process of the next process and performs the same process. If there is no next process at the time of error in step S132 (NO in S132), the error process is terminated, the process proceeds to step S108, and the same process is performed.

  On the other hand, if an error is detected in step S126 before normal completion in step S128 (YES in S126), the task status management unit 104 records an error code in the task status storage unit 122 (S134), and the process proceeds to step S122. Go ahead and do the same.

  If the process for the part is completed in step S122 (YES in S122), the process proceeds to step S112, where it is determined whether there is a next part and the same process is performed.

  As a result of the above processing, error recording is performed on the component part in which an error has occurred, and even if an error occurs in any of the parts, the processing of the next part is performed. Batch processing for creating mesh data for CAE analysis can be performed.

  Further, since error recording is performed for each part for each process, an operator or the like can later process the part in which the error has occurred. Thereby, the period concerning the process which produces | generates the mesh data for CAE analysis from CAD data of an analysis target object can be shortened.

  In addition, conventionally, in order to shorten the period, a plurality of operators sometimes share work, and there is a problem that it is impossible to manage the progress of the overall processing. However, according to the batch processing system 10 in the present embodiment, the task status management unit 104 of the batch processing unit 100 records the task statuses of all parts in the task status storage unit 122, so that the progress of the overall processing is performed. Can also be managed.

  Each component of the batch processing system 10 illustrated in FIG. 1 is not a hardware unit configuration but a functional unit block. Each component of the batch processing system 10 is centered on an arbitrary computer CPU, memory, a program for realizing the components shown in the figure loaded in the memory, a storage unit such as a hard disk for storing the program, and a network connection interface. It is realized by any combination of hardware and software. It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.

  In the above embodiment, the task status storage unit 122 and the parts list storage unit 220 are described separately. However, they may be configured to be displayed together. For example, task status information is stored in the parts list storage unit. The configuration added to 220 may be adopted.

  In the above embodiment, only one mesh data creation processing unit 200 is shown. However, the batch processing system 10 may include a plurality of mesh data creation processing units 200. By causing the plurality of mesh data creation processing units 200 to perform mesh data creation processing in parallel, the processing period can be further shortened. Even in this case, the same effect as described above can be obtained by managing the processing status of each mesh data creation processing unit 200 by the batch processing unit 100.
