FIG. 1 shows a flowchart of an example of a modal analysis simulation model building method according to an embodiment of the invention. The execution main body of the method of the embodiment of the invention can be various mobile terminals with display functions.

As shown in fig. 1, in step 110, a mesh model is obtained. The mesh model may be determined in various ways, and should not be limited herein, for example, the structural model may be constructed by three-dimensional design software such as cata, and the corresponding mesh model may be obtained by a meshing process.

In step 120, a first modality parameter setting control is displayed. Here, the first modality parameter setting control is configured with the corresponding general-type modality parameter. Illustratively, a first modality parameter setting control may be displayed on a user interface of the mobile terminal.

In step 130, when the user operation for the first modal parameter setting control is detected, configuring the general type modal parameter corresponding to the first modal parameter setting control for the grid model to construct a modal analysis simulation model. Here, the modal simulation model may represent a model that can be recognized by a solver, and for example, the modal simulation model may be input to the solver to be solved, so as to output a corresponding analysis report.

In an example of the embodiment of the present invention, all parameters (that is, all parameters are general-type parameters) required in the process of constructing the modal analysis simulation model are configured in the first modal parameter setting control, and the automatic setting of the grid model to the corresponding modal analysis simulation model can be realized by operating the first modal parameter setting control. In another example of the embodiment of the present invention, the first modal parameter setting control may be configured with a part of parameters required in a process of constructing a modal analysis simulation model, and a simulation worker only needs to input a small number of parameters to complete configuration operation on the modal analysis simulation model, thereby improving construction efficiency of the modal analysis simulation model.

It should be noted that the process of constructing the modal analysis simulation model mainly includes the steps of defining boundary conditions, setting modal solution parameters, creating modal analysis, and setting parameters of a calculation control card. In an example of the embodiment of the present invention, the parameters involved in each step are preset, and after the first-modality parameter setting control is operated, each parameter setting step may be automatically executed.

In some implementations, a plurality of boundary condition defining controls may be displayed on the mobile terminal. Here, each boundary condition defining control is configured with boundary condition constraints of corresponding direction dimensions, such as an X-axis direction movement constraint, a Y-axis direction movement constraint, a Z-axis direction movement constraint, an X-axis direction rotation constraint, a Y-axis direction rotation constraint, a Z-axis direction rotation constraint, and the like. Further, when a user selection operation for the boundary condition bounding control is detected, the boundary condition of the mesh model may be configured based on the boundary condition constraints in the direction dimension corresponding to the selected boundary condition bounding control. For example, when the simulator selects the control corresponding to the Y-axis directional movement constraint, a constraint operation may be performed on the corresponding directional dimension of the selected boundary condition control, for example, the grid model is constrained to move on the Y-axis. Therefore, simulation personnel can set the constraint aiming at the grid model in the dimension of the specific direction by selecting the specific boundary condition defining control, the operation is simple and convenient, and the construction efficiency of the modal analysis simulation model can be improved.

In some implementations, a step creation control can be displayed. In addition, when user operation for the step creation control is detected, a solution analysis step can be created based on the general type parameters corresponding to the step creation control. For example, a solution analysis step may be created by using general type parameters corresponding to the step-by-step creation control and combining boundary condition constraints and modal computation orders (for example, preset, obtained by performing modal performance evaluation on a grid model, or customized by a simulation worker). Therefore, the simulation personnel is not required to additionally configure the relevant parameters in the solving and analyzing step, and the establishing process of the solving and analyzing step is simplified.

In some implementations, a card creation control is displayed. Here, the card creation control is configured with a solver format. Accordingly, when a user operation for the card creation control is detected, a solver calculation control card can be created according to a solver format configured by the card creation control. Therefore, the creation operation of solving analysis steps can be automatically completed directly by operating the control without the need of knowing the format of the solver by a simulation person, and the configuration time of the solver calculation control card is shortened.

In another example of the embodiment of the present invention, after the first-modality parameter setting control is operated, the parameters involved in some steps need to be personalized, and at this time, part of the parameter setting steps in the above-described building process may be performed.

In particular, a second modality parameter setting control may be displayed. Here, the second-modality parameter setting control is used to receive a user input operation, and for example, the second-modality parameter setting control may be an input box. Further, when a user input operation for the second modality parameter setting control is detected, the mesh model may be configured based on the user input information. Therefore, the modal parameters of the modal analysis simulation model can be set in a personalized manner by inputting information by a user, and the requirements of the modal analysis simulation model under diversified scenes can be met.

In some implementations, a modality order control can be displayed. Further, when a user input operation for the modal order control is detected, the modal orders of the grid model are configured based on the user input information. Therefore, simulation personnel can set the modal order of the network model according to the actual requirements of the product, so that the constructed modal simulation analysis model has a wider application range.

FIG. 2 shows a flowchart of an example of a modal analysis simulation model building method according to an embodiment of the invention.

As shown in fig. 2, in step 210, the mobile terminal reads the mesh model. Regarding the process of constructing and designing the mesh model, various approaches such as some approaches in the related art can be adopted, and should not be limited herein.

In step 220, the mobile terminal acquires boundary condition constraints. Illustratively, the simulator may analyze whether the grid model employs a free or constrained modality according to the simulation specification, and the simulator may select a particular directional dimension as a boundary condition constraint.

FIG. 3 is a schematic diagram of a user interface suitable for applying an example of a modal analysis simulation model building method of an embodiment of the present invention. As shown in fig. 3, the controls dof 1-dof 6 may respectively represent full constraints for nodes in the mesh model, e.g., dof1 may represent an X-axis direction movement constraint, dof2 may represent a Y-axis direction movement constraint, dof3 may represent a Z-axis direction movement constraint, dof4 may represent an X-axis direction rotation constraint, dof5 may represent a Y-axis direction rotation constraint, and dof6 may represent a Z-axis direction rotation constraint. In addition, if the simulator desires to select a free mode, the above-mentioned controls dof1 to dof6 may not be clicked. Here, the "Create SPC" control may be configured with a boundary condition determination module that determines whether constraints need to be created, and calculates free modalities if not. For example, after the simulator can click on the "Create SPC" control, the mobile terminal can configure the boundary conditions of the grid model using the boundary condition constraints in the selected direction dimension.

In step 230, the mobile terminal acquires a modal calculation order. For example, a simulator may formulate a modal performance evaluation index of the grid model, design a modal calculation order, and set the modal calculation order by operating the mobile terminal. With reference to fig. 3, it is described that when a simulator can set a modal computation order corresponding to the grid model in the "NU" control, the personalized requirements of the grid model under different modal analysis scenarios are met.

In step 240, the mobile terminal determines modal load settings for the mesh model. As explained in connection with fig. 3, the Create LOAD control may be configured with a modal solution parameter determination module for configuring the order of the required computational mode for the grid model. For example, after the simulator clicks the Create LOAD control, the mobile terminal may complete modal solution of EIGRL card (modal LOAD) settings.

In step 250, the mobile terminal determines a calculation control card (or a general card for solution control, output, and the like) suitable for creating the grid model, and outputs a corresponding modal analysis simulation model. The "Create STEP" control may be configured with an analysis STEP creation module and a calculation control card creation module, and when a simulation worker clicks the control, the simulation worker may automatically configure corresponding modal analysis STEPs and calculation control cards for the grid model, for example, automatically Create solution analysis STEPs according to boundary conditions and modal calculation orders, and automatically Create a calculation control card according to a pre-stored format of the solver, without setting parameters by the simulation worker, or without the simulation worker knowing specific parameters (for example, format parameters) of the solver, which is convenient to operate and can greatly improve the efficiency of the modal analysis simulation model.

Further, the modal analysis simulation model may be input to a solver, so that the solver performs a post-processing procedure, and outputs a corresponding modal analysis report.

In the embodiment of the invention, each modal parameter setting control (such as the first modal parameter setting control and the second modal parameter setting control) is set in the same user interface, so that parameters required to be input for modal analysis are simplified, and meanwhile, general parameters and related cards are automatically set. Therefore, the automation of modal simulation model building is realized, the dependence degree on a solver and the operation threshold of modal simulation analysis are reduced, and the simulation efficiency is improved.

In some application scenarios, universal preprocessing software Hypermesh can be adopted for customization and development, and a professional modal simulation analysis system is constructed. Illustratively, different operation steps in the modal simulation analysis process can be integrated and configured by using a TCL/TK scripting language development technology, for example, boundary conditions, modal solution parameters, modal analysis steps, solution and output control cards are configured in a modularization mode to form corresponding controls, a template-based specialized building model environment is constructed, the modal simulation process is standardized, the model building efficiency is improved, modal simulation input parameters are simplified, the use threshold of a NASTRAN solver can be lowered, the efficiency of simulation calculation is improved, and errors are not prone to occur.
