The following describes the technical scheme of the embodiments of the present application in detail with reference to the accompanying drawings.
Fig. 1 is a flow chart of a simulation solving method of a composite material region according to an embodiment of the present application. Referring to fig. 1, the composite region comprises a number of geometric regions, and the method comprises at least the steps of:
step 101, obtaining area information of each geometric area;
in the embodiment of the present application, before performing simulation solution on an object to be simulated, a model to be solved corresponding to the object to be simulated is generally required to be constructed, then the solution model corresponding to the object to be simulated is processed, if the object to be simulated is a composite material region, the model to be solved for the composite material region may be constructed, then the model to be solved is split, a plurality of geometric regions are obtained, and then region information of each geometric region is obtained.
Alternatively, the composite regions may be regions composed of different ferromagnetic materials, including but not limited to soft magnetic, hard magnetic, and the like. The geometric region may be an arbitrarily shaped region formed of a single ferromagnetic material, for example, the geometric region may be a region corresponding to a circular ferromagnetic material, a region corresponding to a square ferromagnetic material. The region information refers to information such as a material type of the geometric region, a boundary point, a boundary line, and a geometric shape formed by the boundary point or the boundary line.
As an example, the region information of each geometric region may be obtained by using an electromagnetic material constitutive model for ferromagnetic materials, which is a model representing constitutive relations of ferromagnetic materials, and in actual electromagnetic simulation, material constitutive may be rapidly added and defined by the electromagnetic material constitutive model, and simulation analysis is performed on a model to be solved.
The construction process of the electromagnetic material constitutive model can comprise the following steps:
first, an initial constitutive model is established: and quickly adding or defining a material structure in electromagnetic simulation, defining various parameters in the material structure by combining an actual solving problem or solving process, then correlating the various parameters with corresponding items in electromagnetic correlation equations, designing grammar matching sentences by utilizing the various parameters and the electromagnetic correlation equations, forming a model script by utilizing a plurality of grammar matching sentences, and finally modeling according to the various parameters, the electromagnetic correlation equations and the model script to obtain an initial constitutive model.
Secondly, fitting and verifying the initial constitutive model to obtain an electromagnetic material constitutive model: and carrying out parameter fitting on the initial constitutive model and experimental data by adopting a fitting algorithm, after the parameter fitting is finished, verifying the model, and if the accuracy of the model meets the actual requirement, indicating that the model construction is finished, and taking the model as the electromagnetic material constitutive model.

Step 102, calling a target model script corresponding to the geometric region according to the region information, wherein the target model script is associated with at least one simulation component;
in the embodiment of the application, the electromagnetic material constitutive model can call a target model script corresponding to the geometric region according to the region information, and call at least one simulation component associated with the target model script.
Alternatively, the target model script may be a collection of statements conforming to a predefined matching statement that is associated with at least one simulation component.
The matching statement is a specific combination mode of matching keywords, and at least comprises contents such as a calling interface of the simulation component, coefficients or variables corresponding to the simulation component and the like besides the keywords of the simulation component, and each simulation component is designed with a corresponding matching statement.
The simulation component can be a finite element basic component under a certain physical field, and can obtain data such as a calling interface, coefficients or variables corresponding to the simulation component and the like by analyzing matching sentences in the target model script, and then call the simulation component through the data.
As an example, in the field of ferromagnetic simulation, there are many component sets, such as a set of calculation components of a vector J-a hysteresis model, a set of calculation components of a static hysteresis model, a set of calculation components of an energy-based hysteresis model, and the like, and the simulation components may be finite element basic components in these component sets, such as a simulation component may be a calculation non-hysteresis magnetization component, a calculation total magnetization variation component, a calculation magnetic field variation component, a calculation magnetic density variation component, and a call interface component in the set of calculation components of a vector J-a hysteresis model, a non-hysteresis characteristic curve component in the set of calculation components of an energy-based hysteresis model, a related vector update component, a related tensor construction component, a call interface component, and the like, and may also be various interpolation components, such as a linear interpolation component, a bilinear interpolation component, and the like.
And step 103, carrying out simulation solution on each geometric area by adopting a simulation component to obtain simulation analysis data aiming at the composite material area.
In the embodiment of the application, after the electromagnetic material constitutive model determines the target model script according to the region information, a simulation component associated with the target model script can be called, and then the simulation component is adopted to purposefully perform simulation solution on each geometric region to obtain simulation analysis data aiming at the composite material region.
Alternatively, the simulation analysis data may be simulation results obtained by performing simulation solution on the geometric region by using a simulation component, such as a magnetic density distribution, a current density distribution, and the like.
In the embodiment of the application, the electromagnetic material constitutive model can split a composite material region into a plurality of geometric regions, obtain region information of each geometric region, call a target model script corresponding to the geometric regions according to the region information, and the target model script comprises at least one simulation component, and perform simulation solution on each geometric region by adopting the simulation component to obtain simulation analysis data aiming at the composite material region.
On the one hand, when the electromagnetic material constitutive model faces a composite material area composed of a plurality of materials, the whole composite material area can be divided into a plurality of local areas by dividing the composite material area composed of the plurality of materials into a plurality of geometric areas, and each geometric area can be solved in a targeted manner.
On the other hand, the corresponding target model script is called according to the region information of each geometric region, the simulation component associated with the target model script is called, and the adaptive simulation component is adopted to perform simulation solution on each geometric region respectively, so that the simulation solution mode of the electromagnetic material constitutive model is enriched, universality is achieved, and comprehensive simulation processing is achieved.
FIG. 2 is a flow chart of a simulation solution method for a composite region according to another embodiment of the present application. Fig. 2 illustrates in more detail the technical solution of the embodiment of the present application with respect to fig. 1, and the method may include the following steps:
step 201, obtaining area information of each geometric area;
in this embodiment of the present application, the electromagnetic material constitutive model may obtain the region information of each geometric region from a mesh file, where the mesh file refers to a file generated when the geometric region is meshed, and if the composite material region is partitioned into a plurality of geometric regions, the mesh file includes at least attribute information of each geometric region, such as a geometric shape, a mesh unit, a mesh number, a mesh type, and a physical quantity corresponding to the geometric region.
In an alternative example, before the region information of each geometric region is acquired, the electromagnetic material constitutive model can acquire the material type and the construction mode of the composite material region, then split the composite material region according to the construction mode to obtain a plurality of geometric regions, and the electromagnetic material constitutive model can pertinently adopt different simulation solving modes for different geometric regions, so that the electromagnetic material constitutive model is prevented from being limited by the material type of a simulation object when the electromagnetic material constitutive model carries out simulation solving on the composite material region, and the universality of the electromagnetic material constitutive model is further improved by improving the adaptation degree of the electromagnetic material constitutive model and the composite material region.
Alternatively, the material type may be a magnet material, and the construction mode may be a region closing mode, and different construction modes correspond to different geometric shapes, such as a circle, a square, an irregular shape, and the like.
Referring to fig. 3, fig. 3 is a schematic view of each geometric area in the composite area shown in the embodiment of the present application, where the composite area is split into an Air geometric area, a ball1 geometric area, a ball2 geometric area, a block1 geometric area, and a block2 geometric area according to a construction manner and a material type.
Wherein there are B1 and B2 regions in the block2 geometry region, the B1 and B2 regions being spatially connected, but the B1 and B2 regions being of different material types, different material support sets are defined for the B1 and B2 regions, e.g. the B1 region in the block2 geometry region corresponds to the material support set (1) and the B2 region corresponds to the material support set (2).
While the ball1 geometry region and the ball2 geometry region are spatially separated, the ball1 geometry region and the ball2 geometry region belong to the same material type, so that the same material support set is defined for the ball1 geometry region and the ball2 geometry region, such as the ball1 geometry region and the ball2 geometry region correspond to the material support set (3).
The material types of the block1 geometric region and other geometric regions are different, so that a material support set different from the other geometric regions can be defined for defining the block1 geometric region, such as the material support set (4) corresponding to the block1 geometric region.
Step 202, acquiring material types of each geometric region and a material support set associated with the material types, wherein the material support set is used for being associated with a model script;
in the embodiment of the application, different material types correspond to different material support sets, so that the corresponding material support sets can be determined according to the material types of the geometric regions, and the different material support sets also correspond to different model scripts.
Optionally, the following relationships exist among the geometric region, the material support set, the target model script, and the simulation component:
the first association relationship is: and defining or associating the corresponding support set according to the material type of the geometric region, associating the material type of the geometric region with the material support set, and generating a support set mapping relation.
The second association relationship is: the material support set is associated with a model script, a script mapping relationship is generated, for example, the material support set (1) is associated with a first model script, and the material support set (2) is associated with a second model script.
The third association relationship is: the model script is associated with each simulation component by a keyword, generating a component mapping relationship, for example, the model script includes a first keyword associated with the first simulation component and a second keyword associated with the second simulation component.
As an example, in addition to determining the material support set according to the material type of the geometric region, the corresponding material support set may be determined according to the geometric shape of the geometric region, for example, a circular region and a square region may be included in a certain geometric region, after determining the geometric shape of the geometric region, the geometric region may be divided into two independent regions according to the geometric shape, each region is taken as an independent object, and the support set associated with the object may be acquired through the geometric shape, so as to determine the model script associated with each object.
Step 203, calling a target model script corresponding to the geometric area according to the material support set, wherein the target model script is associated with at least one simulation component;
in the embodiment of the application, a script mapping relation is constructed in advance based on the association relation between the material support set and the target model script, so as to be used for mapping a certain model script through the material support set.
Alternatively, a material support set refers to a support set of real-valued functions defined on the set, the support set often being bound to the function as a region of action of the function, through which a model script associated therewith can be invoked as a target model script.
In an alternative example, the region information includes a unit sequence number of the geometric region, and invoking the object model script corresponding to the geometric region according to the support set includes the following sub-steps:
s31, carrying out grid division on the geometric area to obtain a plurality of grid cells, wherein each grid cell corresponds to a cell serial number;
referring to fig. 4, fig. 4 is a schematic diagram of a plurality of grid cells shown in the embodiment of the present application, after grid division is performed on each geometric area, a plurality of grid cells may be obtained, and a related technician may number each grid according to actual needs, for example, number each grid cell as 1, 11, 23, 34, 56, 73, etc., and the number manner is not limited in this application.
