In one embodiment, as shown in fig. 1, there is provided a section attribute assigning method of a finite element model, which is applied to a terminal execution example for explanation, including the steps of:
step S110, a model component list corresponding to the finite element model and a section attribute list corresponding to the finite element model are obtained.
In the step, the model component list corresponding to the finite element model refers to a component list corresponding to the finite element model and containing all components in the finite element model; the section attribute list corresponding to the finite element model refers to a section attribute list corresponding to the finite element model and containing a plurality of section attribute data, wherein the section attribute data is section attribute data for endowing each part in the finite element model with a corresponding section attribute.
In practical application, the finite element model can be a finite element model created by adopting finite element software Abaqus for engineering simulation; the specific way to obtain the model component list corresponding to the finite element model may be to import or create a component geometric model containing each component corresponding to the current finite element model, where the component names of each component in the component geometric model all follow a uniform naming format, for example, component name-section type-section thickness-material (naming format of shell-type component), and component name-material (naming format of solid-type component); the cross section attribute list corresponding to the finite element model may be a cross section attribute list stored in a cross section attribute database, or a cross section attribute list created through a GUI interface of software, or a cross section attribute list copied from other finite element models, and each cross section attribute data in the cross section attribute list may follow a uniform naming format, for example, a cross section type-cross section thickness-material (shell type cross section attribute data), and a cross section type-material (solid type cross section attribute data).
Step S120, updating the section attribute list based on the data matching condition between the part names of all the parts in the model part list and the section attribute list, and obtaining an updated section attribute list.
In this step, the model component list, that is, the model component list corresponding to the finite element model, refers to the component list corresponding to the finite element model and including each component in the finite element model; the section attribute list, namely the section attribute list corresponding to the finite element model, refers to the section attribute list corresponding to the finite element model and containing a plurality of section attribute data.
In practical application, a specific way to obtain the data matching condition between the part names of the parts in the model part list and the section attribute list may be to confirm whether section attribute data representing relevant information such as section thickness, material and the like in the part names of the parts in the model part list exists in the section attribute list.
And step S130, defining objects for the attributes corresponding to each component in the model component list by adopting the updated section attribute list, and endowing the corresponding section attributes to obtain a plurality of components endowed with the section attributes.
In the step, the updated section attribute list refers to an updated section attribute list obtained by updating the section attribute list based on the data matching condition between the part names of all the parts in the model part list and the section attribute list; the model component list, that is, the model component list corresponding to the finite element model, refers to the component list corresponding to the finite element model and including each component in the finite element model.
In practical application, the updated section attribute list is adopted to define objects for the attributes corresponding to each component in the model component list, and the specific mode of endowing the corresponding section attribute can be to endow the corresponding section attribute for the attribute definition object corresponding to each component in the model component list based on the corresponding relation between the component name of each component in the model component list and the updated section attribute list; the correspondence between the component names of the respective components in the model component list and the updated section attribute list may be determined by sequentially matching the component names of the respective components in the model component list with the attribute names of the respective section attribute data in the updated section attribute list.
In the method for assigning the cross-sectional attribute of the finite element model, a model component list corresponding to the finite element model and a cross-sectional attribute list corresponding to the finite element model are acquired. Then, based on the data matching condition between the part names of the parts in the model part list and the section attribute list, updating the section attribute list to obtain an updated section attribute list. And finally, adopting the updated section attribute list to define objects for the attributes corresponding to each component in the model component list, endowing the corresponding section attributes, and obtaining a plurality of components endowed with the section attributes. According to the application, based on the corresponding relation between the attribute names of the section attribute data and the part names of the parts in the finite element model, the corresponding section attribute is automatically endowed to the parts in the finite element model, so that the efficiency of endowing the section attribute to the parts in the finite element model can be improved, the misoperation phenomenon possibly caused by manual operation one by one can be avoided, and the accuracy of the operation result of endowing the section attribute to the parts in the finite element model is further effectively improved.
For the specific way of updating the cross section property list, in one embodiment, the cross section property list includes a cross section property data list and a material property data list; as shown in fig. 2, the step S120 specifically includes:
step S210, the section attribute names carried by the components are matched with the attribute names of the section attribute data in the section attribute list in sequence.
In the step, the section attribute names of all the parts refer to the section attribute names of all the parts in the part names of the parts in the model part list corresponding to the finite element model; the section attribute list, namely the section attribute list corresponding to the finite element model, refers to the section attribute list corresponding to the finite element model and containing a plurality of section attribute data.
In practical application, the specific purpose of matching each component name with the attribute names of each section attribute data in the section attribute list in sequence may be to confirm whether there is an attribute name consistent with the section attribute name carried by each component in the model component list corresponding to the finite element model in the attribute names of each section attribute data in the section attribute list.
Step S220, when the attribute names are inconsistent with the section attribute names carried by the current component, the section attribute names carried by the current component are used as the attribute names of the newly added section attribute data in the section attribute list.
In this step, each attribute name refers to an attribute name of each section attribute data in the section attribute list; the section attribute name carried by the current component refers to the section attribute name carried in the component name of a certain component in the model component list, which is currently matched with the attribute name of each section attribute data in the section attribute list; each attribute name is inconsistent with the section attribute name carried by the current component, which means that among the attribute names of each section attribute data in the section attribute list, there is no attribute name consistent with the section attribute name carried by the current component.
In practical application, the newly added section attribute data can be created by defining a mode of automatically creating the section attribute function, and on the basis that the section attribute list comprises a shell section attribute data list and a solid section attribute data list, when attribute data are newly added for the two data lists, the creation can be performed by respectively defining a mode of automatically creating the shell section attribute function and an automatic creating the solid section attribute function.
Step S230, determining the material attribute corresponding to the newly added section attribute data based on the matching result of the attribute name of the newly added section attribute data and the material name of each material attribute data in the material attribute data list.
In this step, the attribute name of the newly added section attribute data refers to the attribute name of the newly added section attribute data in the section attribute list; the matching result of the attribute name of the newly added section attribute data with the material name of each material attribute data in the material attribute data list means a matching result for confirming whether or not there is a material name matching with the material definition in the attribute name of the newly added section attribute data among the material names of each material attribute data in the material attribute data list.
According to the embodiment, whether the section attribute data need to be newly added is determined based on the matching condition between the section attribute names of all the parts in the model part list and the attribute names of all the section attribute data in the section attribute list, and the attribute names and the material attribute of the newly added section attribute data are confirmed, so that the efficiency of updating the section attribute data list is effectively improved, and the efficiency of endowing the section attribute to all the parts in the finite element model is further ensured.
For a specific manner of determining the material attribute corresponding to the newly added section attribute data, in one embodiment, as shown in fig. 3, the step S230 specifically includes:
step S310, if any material name does not exist and is consistent with the material definition in the attribute name of the newly added section attribute data, determining the material attribute corresponding to the newly added section attribute data based on the preset naming standard.
In the step, the absence of any material name consistent with the material definition in the attribute name of the newly added section attribute data means that the absence of any material name consistent with the material definition in the attribute name of the newly added section attribute data in the material names of the respective material attribute data in the material attribute data list; the preset naming standard refers to a preset naming standard for naming the material attribute corresponding to the newly added section attribute data when any material name is not consistent with the material definition in the attribute name of the newly added section attribute data.
In practical applications, a specific manner of determining the material attribute corresponding to the newly added section attribute data based on the preset naming standard may be to name the material attribute corresponding to the newly added section attribute data as "nofindwaterial" when there is no coincidence between any material name and the material definition in the attribute name of the newly added section attribute data (i.e., the preset naming standard for naming the material attribute corresponding to the newly added section attribute data is "nofindwaterial").
In step S320, if any material name matches the material definition in the attribute name of the new section attribute data, the material attribute corresponding to the new section attribute data is determined based on the material definition in the attribute name of the new section attribute data.
In the step, the existence of any material name is consistent with the material definition in the attribute name of the newly added section attribute data, namely, the existence of any material name in the material names of the material attribute data in the material attribute data list is consistent with the material definition in the attribute name of the newly added section attribute data; determining a material attribute corresponding to the newly added section attribute data based on the material definition in the attribute name of the newly added section attribute data refers to determining the material definition in the attribute name of the section attribute data as the material attribute corresponding to the newly added section attribute data.
According to the embodiment, by judging whether any material name is consistent with the material definition in the attribute name of the newly-added section attribute data or not, the concrete expression form of the material attribute corresponding to the newly-added section attribute data is determined, so that the efficiency of determining the material attribute corresponding to the newly-added section attribute data is improved, and the data accuracy of the newly-added section attribute data is effectively ensured.
For a specific way of classifying data for the section attribute list and the model component list, in one embodiment, as shown in fig. 4, after the step S110, the method further includes:
step S410, according to the section types represented by the attribute names of the section attribute data in the section attribute list, classifying the section attribute list to obtain a shell section attribute list and a solid section attribute list.
In this step, the data classification is performed on the cross section attribute list according to the cross section types represented by the attribute names of the cross section attribute data in the cross section attribute list, that is, the cross section attribute list may be data classified based on the difference of the cross section types represented by the attribute names of the cross section attribute data in the cross section attribute list because the attribute names of the cross section attribute data in the cross section attribute list all have the related information representing the cross section types to which the cross section attribute data belongs; the shell-type section attribute list is a shell-type section attribute list formed by combining section type which is characterized by attribute names of section attribute data in the section attribute list and is section attribute data of a shell-type section; the solid section attribute list is a solid section attribute list formed by combining section attribute data of which the section types represented by attribute names of section attribute data in the section attribute list are solid sections.
In practical application, assuming that each section attribute data in the section attribute list conforms to a unified naming format, namely a section type-section thickness-material (shell-type section attribute data) and a section type-material (entity-type section attribute data), each section attribute data in a format of "section type-section thickness-material" can be included in the shell-type section attribute list, and each section attribute data in a format of "section type-material" can be included in a format of "section type-section thickness-material" (i.e., the section type characterized by the attribute name is an entity-type section).
Step S420, according to the naming format of the component names of the components in the model component list, classifying the data of the model component list to obtain a shell type component list and a solid type component list.
In this step, the data classification is performed on the model component list according to the naming format of the component names of the components in the model component list, which means that the data classification is performed on the model component list according to the naming format of the component names of the components in the model component list because the naming format of the component names of the model components corresponding to different section types of the model component list is different; the shell type part list is formed by combining all parts with the corresponding section types of shell type sections in the model part list; the solid type part list is a solid type part list formed by combining parts with solid type cross sections corresponding to the cross section types in the model part list.
In practical applications, assuming that the component names of the components in the model component list all follow a unified naming format, that is, the component name-section type-section thickness-material (naming format of shell-type components) and the component name-material (naming format of entity-type components), each component with the naming format of "component name-section type-section thickness-material" (naming format of shell-type components) may be included in the shell-type component list, and each component with the naming format of "component name-material" (naming format of entity-type components) may be included in the entity-type component list.
The above embodiment effectively improves the efficiency of assigning the section attribute to each component in the finite element model by classifying the section attribute list and the model component list according to the attribute name of each section attribute data in the section attribute list and the naming format of the component name of each component in the model component list.
For a particular way of incorporating a component into a corresponding set of model components, in one embodiment, the above method further comprises:
each component is incorporated into a corresponding set of model components.
The corresponding model component set refers to a model component set for placing corresponding components, and the model component set may be formed by corresponding components not endowed with section properties (i.e., corresponding components selected from each component in a model component list corresponding to the finite element model) or corresponding components endowed with section properties (i.e., corresponding components selected from each component endowed with section properties), and when the model component set is used subsequently, the model component set may be used to characterize corresponding components contained in the model component set.
The embodiment effectively improves the subsequent use efficiency of the corresponding parts in the model part set by bringing the parts into the corresponding model part set.
For the specific manner in which the respective cross-sectional properties are assigned to the property definition objects corresponding to each component, in one embodiment, the property definition objects include a component geometry and a component grid; as shown in fig. 5, the step S130 specifically includes:
step S510, when the type of any component is a geometric body, the updated section attribute list is adopted to assign corresponding section attributes to the component geometric body corresponding to the current component.
In the step, the type of any part is a geometric body, which means that the type of any part in the model part list is a geometric body; the component geometry corresponding to the current component refers to that when the type of any component in the model component list is geometry, the attribute definition object corresponding to the component is the component geometry.
Step S520, when the type of any component is a grid, the updated section attribute list is adopted to endow the corresponding section attribute to the component grid corresponding to the current component.
In the step, the type of any part is a grid, which means that the type of any part in the model part list is a grid; the component mesh corresponding to the current component refers to that, in the case where the type of any component in the model component list is a mesh, the attribute definition object corresponding to the component is the component mesh.
In practical applications, after steps S510 to S520, a function for creating a component set may be defined, so that after the type of each component given with the cross-sectional attribute is determined (that is, each component is determined to belong to a geometry type or a grid type), a component set of a corresponding type is created (that is, a component of a geometry type is created, a component set of a geometry type is created, a component of a grid type is created, and a component set of a grid type is created).
According to the embodiment, the accuracy of the operation result of endowing the section attribute to each component in the finite element model is effectively ensured by determining the attribute definition object corresponding to each component based on the type of each component and endowing the corresponding section attribute to each attribute definition object.
It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in the flowcharts described in the above embodiments may include a plurality of steps or a plurality of stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of the steps or stages is not necessarily performed sequentially, but may be performed alternately or alternately with at least some of the other steps or stages.

The implementation of the solution provided by the device is similar to the implementation described in the above method, so the specific limitation in the embodiments of the cross-section attribute imparting device for one or more finite element models provided below may be referred to the limitation of the cross-section attribute imparting method for a finite element model hereinabove, and will not be repeated here.
