Description

Technical Field

[0001] This invention relates to the field of controlled nuclear fusion technology, specifically to an electromagnetic force simulation method, system, and electronic equipment for a nuclear fusion device. Background Technology

[0002] Tokamak devices are currently important experimental devices for exploring magnetic confinement fusion. The magnetic confinement is mainly generated by coils such as toroidal field coils, poloidal field coils, and central solenoid coils. The electromagnetic force generated by the coils when energized can cause the coils to deform. This electromagnetic force can include centripetal force, overturning force, and expansion force. The centripetal force drives the coil to move towards the center; the overturning force causes the coil to twist; and the expansion force causes the coil to expand radially. In addition, the bottom of the toroidal field coil may also be equipped with a soft board and a return coil. However, the bottom soft board and return coil structures are asymmetrical. Therefore, in the detailed study of electromagnetic force simulation calculations, the model cannot be simplified by periodic symmetry.

[0003] Typically, when performing electromagnetic force simulations, the electromagnetic forces calculated by Maxwell software are automatically coupled to the structural simulation software Mechanical via the Workbench platform. However, because tokamak devices have multiple structures that generate electromagnetic forces and the structures are asymmetrical, the models to be analyzed are large. Using the Workbench platform often causes the software to crash, making it difficult to complete the simulation calculations for nuclear fusion devices. In some related technologies, electromagnetic forces are often extracted manually and then added to Mechanical as loads for simulation calculations. However, the manual extraction and addition process often requires setting a large number of parameters, which takes a lot of time, resulting in low simulation efficiency and poor accuracy.

[0004] Therefore, improving the efficiency and accuracy of simulation calculations for nuclear fusion devices has become an urgent technical problem to be solved. Summary of the Invention

[0013] Secondly, embodiments of the present invention propose an electromagnetic force simulation system for a nuclear fusion device, comprising: an SCDM module, used to name the model to be analyzed that generates electromagnetic force in the nuclear fusion device in SCDM, obtaining a model file with a model name, wherein the model to be analyzed includes an asymmetric structure model; a Maxwell module, used to cyclically load the model file in SCDM using Maxwell, automatically define electromagnetic force names based on the model names, and cyclically set the relevant parameters of the electromagnetic force corresponding to each model to be analyzed according to the model names and the electromagnetic force names, obtaining an electromagnetic force parameter file, wherein the relevant parameters are the relevant parameters involved in solving the electromagnetic force; reading the electromagnetic force parameter file in Maxwell, and sequentially solving the electromagnetic force corresponding to each model to be analyzed for the electromagnetic force parameter file, obtaining an electromagnetic force data file; and a Mechanical module, used to read the model file in SCDM and the electromagnetic force data file in Maxwell respectively using Mechanical, and load the electromagnetic force in the electromagnetic force data file into the model to be analyzed in the model file according to the model name for structural simulation analysis.

[0020] The electromagnetic force simulation method for nuclear fusion devices provided by this invention involves naming and grouping the models to be analyzed using SCDM to obtain model files. These model files are then read in Maxwell, and the electromagnetic forces are named according to the model names within the files, ensuring a one-to-one correspondence between the electromagnetic forces and the models to be analyzed. This facilitates the addition and analysis of subsequent loads. After naming the electromagnetic forces, the relevant parameters for the electromagnetic forces to be solved are automatically set according to the preset parameters required for calculating the corresponding electromagnetic forces, based on the model names and electromagnetic force names. This forms an electromagnetic force parameter file with automatically set electromagnetic force parameters, enabling the automatic setting of electromagnetic forces corresponding to custom models.

This electromagnetic force data file contains all the electromagnetic forces set in the Maxwell software, as well as the attributes corresponding to each electromagnetic force. Finally, in Mechanical, the model to be analyzed in SCDM is fused with the electromagnetic force data in Maxwell, one-to-one, thus completing the loading of electromagnetic force loads on the model to be analyzed. This allows for structural simulation analysis and the automatic setting of electromagnetic forces on the model. Electromagnetic forces in each direction of the model to be analyzed are automatically extracted and saved to a text file in a specified format. During structural analysis, the acquired electromagnetic force loads are automatically set, eliminating the need for manual setting of numerous parameters, improving simulation efficiency, reducing errors, and increasing accuracy.

These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention.

[0028] Please refer to Figure 1 , Figure 1 This invention provides an electromagnetic force simulation method for a nuclear fusion device. This method simulates and analyzes the coil structure by calculating the electromagnetic force generated by coils in the nuclear fusion device. In this embodiment, the coils may include circumferential field coils, poloidal field coils, and central solenoid coils, etc. The circumferential field coils may include asymmetric structures such as bottom flexible busbars and return coils. The simulation method may include:

[0029] S101. Name the model to be analyzed in the nuclear fusion device that generates electromagnetic force in SCDM to obtain a model file with a model name. The model to be analyzed includes an asymmetric structure model. As an exemplary embodiment, the design file of the nuclear fusion device can be loaded into SCDM. The design file may include the design files of various components in the nuclear fusion device. The structure that can generate electromagnetic force is selected from the design file, and the corresponding geometric model is established in SCDM as the model to be analyzed, or the model of the structure that generates electromagnetic force in the nuclear fusion device is established using SCMD as the model to be analyzed. For example, geometric models can be established separately for the circumferential field coil, the poloidal field coil, and the central solenoid coil. Geometric models also need to be established separately for asymmetric structures such as the bottom soft busbar and the return coil.

[0030] After establishing the geometric model, the established model is named and grouped in SCDM, and the model name of the model to be analyzed is written into a specified text file as the model file.

[0031] S102. Using Maxwell to cyclically load the model files in SCDM, the electromagnetic force names are automatically defined based on the model names, and the relevant parameters of the electromagnetic forces corresponding to each model to be analyzed are sequentially set according to the model names and the electromagnetic force names, resulting in an electromagnetic force parameter file. These relevant parameters are those involved in solving the electromagnetic forces. As an exemplary embodiment, after creating the model file, Maxwell is initialized, the model file is called, the current project is called based on the model file, and the current design is called. In this embodiment, the design files of a nuclear fusion device can also be directly imported, and the project and design can be created based on the design files.

[0032] During the process of reading model files using Maxwell, the electromagnetic force setting module is invoked. This module iteratively loads the model names from the model file. During this loading process, the electromagnetic force names corresponding to the model to be analyzed are redefined based on the model names. For example, the electromagnetic force names can be prefixed or suffixed with the model name to be analyzed, ensuring a one-to-one correspondence between the model to be analyzed and the corresponding electromagnetic force names. This facilitates the addition of subsequent loads and result analysis. Each electromagnetic force name is unique; different electromagnetic force names are not repeated.

[0033] The parameter setting module is invoked to iteratively set the electromagnetic force parameters. In this embodiment, the preset parameters required for calculating the corresponding electromagnetic force can be determined based on the model name and the electromagnetic force name, and the relevant parameters for solving the electromagnetic force can be automatically set. Through iteration, the relevant parameters involved in the electromagnetic force calculation of the model can be uniformly set. In this embodiment, the relevant parameters may include the coordinate system and direction that need to be specified when calculating the electromagnetic force, as well as the electromagnetic force type, which may include virtual work force and Lorentz force. When setting the electromagnetic force, the list of electromagnetic force setting names needs to be exported to a specified file to form an electromagnetic force parameter file. This completes the automatic setting of the defined electromagnetic forces of the model to be analyzed, preparing for the subsequent extraction of electromagnetic forces.

[0034] S103. Read the electromagnetic force parameter file in Maxwell, and solve for the electromagnetic force corresponding to each of the models to be analyzed in sequence for the electromagnetic force parameter file to obtain an electromagnetic force data file. In this embodiment, the analysis and solution module in Maxwell software is called to read the electromagnetic force parameter file and obtain the electromagnetic force name of each electromagnetic force in the electromagnetic force parameter file, and define the text name and format of the exported electromagnetic force data. Then, for each electromagnetic force name in the electromagnetic force parameter file, the electromagnetic force corresponding to each model to be analyzed is solved and exported in sequence, and all electromagnetic forces are added to a list to obtain an electromagnetic force data file. This electromagnetic force data file contains all the electromagnetic forces set in Maxwell software, as well as the attributes corresponding to each electromagnetic force.

[0035] S104. Using Mechanical, read the model file from SCDM and the electromagnetic force data file from Maxwell, respectively, and load the electromagnetic forces from the electromagnetic force data file onto the model to be analyzed in the model file based on the model name for structural simulation analysis. After obtaining the model file in SCDM and the electromagnetic force data file in Maxwell after setting and extracting electromagnetic forces according to the model file, import the model file and electromagnetic force data file into Mechanical. Mechanical reads the model file exported from SCDM, determines the model name and corresponding model for which electromagnetic force loads need to be set according to the model file, and obtains the solution results of the electromagnetic forces corresponding to each model name in the electromagnetic force data file. Load the solution results of the electromagnetic forces onto the corresponding model. After obtaining the structural model and the corresponding electromagnetic force data, use Mechanical to perform structural simulation analysis.

[0036] In this application, the model to be analyzed is named and grouped using SCDM to obtain a model file. This model file is then read by Maxwell, and the electromagnetic forces are named according to the model names in the file, ensuring a one-to-one correspondence between the electromagnetic forces and the models to be analyzed. This facilitates the subsequent addition and analysis of loads. After naming the electromagnetic forces, the relevant parameters for solving the electromagnetic forces are automatically set according to the model names and electromagnetic force names, based on the preset parameters required for calculating the corresponding electromagnetic forces. This forms an electromagnetic force parameter file with automatically set electromagnetic force parameters, enabling the automatic setting of electromagnetic forces corresponding to custom models. Maxwell then reads the electromagnetic force parameter file, solves for each electromagnetic force name in the file, and exports the electromagnetic force corresponding to each model to be analyzed. All electromagnetic forces are added to a list to obtain an electromagnetic force data file. This electromagnetic force data file contains all the electromagnetic forces set in the Maxwell software, as well as the corresponding attributes of each electromagnetic force. Finally, in Mechanical, the models to be analyzed in SCDM and the electromagnetic force data in Maxwell are fused one-to-one, thus completing the loading of electromagnetic force loads on the models to be analyzed. This allows for structural simulation analysis and the automatic setting of electromagnetic forces on the models to be analyzed. Electromagnetic forces in all directions of the model under analysis are automatically extracted and saved to a text file in a specified format. During structural analysis, the acquired electromagnetic force loads are automatically set, eliminating the need to manually set numerous parameters, thus improving simulation efficiency, reducing errors, and increasing accuracy.

[0037] In one embodiment, the model files in SCDM are loaded using Maxwell loops. Electromagnetic force names are automatically defined based on the model names. Then, the relevant parameters of the electromagnetic forces corresponding to each model to be analyzed are sequentially and looped according to the model names and the electromagnetic force names, resulting in an electromagnetic force parameter file including:

[0038] After calling the parameter setting module and the electromagnetic force setting module, the model name in the model file in the SCDM is read and written into the model name list. The model name list is loaded in a loop. During the loop loading, the electromagnetic force setting module automatically defines the electromagnetic force name based on the model name. After the electromagnetic force name is defined, or during the electromagnetic force definition process, the relevant parameters of the electromagnetic force are set in a loop according to the model name and the defined electromagnetic force name, based on the relevant parameters involved in solving the electromagnetic force, and written into the electromagnetic force name list to obtain the electromagnetic force parameter file.

[0039] The relevant parameters may include the coordinate system and direction that need to be specified when calculating electromagnetic force, as well as the type of electromagnetic force, which may include virtual work force and Lorentz force.

[0040] In one embodiment, the relevant parameters involved in solving the electromagnetic force can be preset in advance based on the model name and the electromagnetic force name, and different relevant parameters can be preset for different models of electromagnetic forces or for different types of electromagnetic forces.

[0041] In another embodiment, the relevant parameters can be fixed, that is, the relevant parameters corresponding to all models and electromagnetic forces are the same or fixed. That is, the coordinate system, direction and electromagnetic force type of the electromagnetic force in the loaded model are fixed. After loading the model file and defining the electromagnetic force name, the relevant parameters remain unchanged when setting parameters. The relevant parameters are matched with all electromagnetic forces one by one by the model name and electromagnetic force name through an automated script to automatically complete the setting of the relevant parameters.

[0042] In one embodiment, the process of solving for extracted electromagnetic forces can be carried out as follows: After calling the current design (the specific calling method can be found in the Maxwell method for calling the current design when automatically setting electromagnetic forces described in the above embodiments, and will not be repeated here), the analysis and solution module is called to read the electromagnetic force parameter file and obtain the list of electromagnetic force names in the electromagnetic force parameter file. The text name and format for exporting electromagnetic force data are defined. After defining the text name and format, the electromagnetic forces are exported by calling the data export interface to export the electromagnetic forces corresponding to the model to the specified text file. When exporting electromagnetic forces, they are exported sequentially according to the models to be analyzed. The data in the electromagnetic force parameter file contains software information and the electromagnetic forces in each direction of each model to be analyzed. Therefore, the exported data needs to be filtered. In this embodiment, the electromagnetic forces of each model to be analyzed are filtered sequentially according to the list of electromagnetic force names to obtain the electromagnetic force solution results for each model to be analyzed. The steps of defining the text name and format and exporting electromagnetic force data are executed repeatedly until the electromagnetic forces of all models to be analyzed are exported, and all the electromagnetic force solution results are exported to the electromagnetic force data file. The electromagnetic force data file contains all the electromagnetic forces set in the Maxwell software, that is, the type of each electromagnetic force, as well as the electromagnetic components and resultant force of each electromagnetic force in three directions.

[0043] After naming and grouping the models to be analyzed in SCDM, model files are constructed. After loading the model files in Maxwell, the model names of the models to be analyzed in the model files are loaded iteratively. For each model name, an electromagnetic force name is defined. Based on the electromagnetic force name and model name, the relevant parameters for solving the electromagnetic forces are automatically set. Then, based on the automatically set electromagnetic force parameter file, the corresponding electromagnetic forces are extracted to obtain the corresponding electromagnetic force data file. Using Mechanical to load the model files in SCDM and the electromagnetic force data files extracted from Maxwell ensures a one-to-one correspondence between the model files and electromagnetic forces in Mechanical, including names, parameters, and mesh information. Therefore, in Mechanical, the electromagnetic forces in the electromagnetic force data files can be loaded into the models to be analyzed in the model files based on the model names for structural simulation analysis. Specifically, the model files exported from SCDM are read to obtain the names of the models for which electromagnetic force loads need to be set. Mechanical is used to filter the model files in SCDM and establish model groups, i.e., creating NamedSelection in Mechanical. This process prepares for assigning electromagnetic force loads to specified models. The Mechanical method calls the Maxwell analysis and solver module interface to read the electromagnetic force data file in Maxwell, obtaining the electromagnetic force solution results for each model to be analyzed. Specifically, it extracts the electromagnetic force in each direction corresponding to each electromagnetic force name from the electromagnetic force data file. For example, the electromagnetic force solution results distinguish the X, Y, and Z directions of the electromagnetic force corresponding to each model to be analyzed, as well as the resultant force. Then, it obtains the model grouping NamedSelection established based on the model file in SCDM. Within the specified NamedSelection, it calls the interface for adding electromagnetic forces, adding the electromagnetic force solution results to the model group one by one as loads for the model to be analyzed for simulation calculation. Specifically, based on the model name in the model group, it sequentially defines the electromagnetic force name and electromagnetic force type in the model group, and loads the electromagnetic forces in each direction according to the corresponding electromagnetic force name and electromagnetic force type to obtain the load of the model to be analyzed. This allows for the automatic setting of the electromagnetic forces of the model to be analyzed. The electromagnetic forces in the X, Y, and Z directions of the model to be analyzed are automatically extracted and saved to a text file in a specified format. In structural analysis, the acquired electromagnetic force loads are automatically set, eliminating the need to manually set a large number of parameters, thus improving simulation efficiency, reducing errors, and increasing accuracy.

The relevant parameters are the relevant parameters involved in solving the electromagnetic force. The electromagnetic force parameter file is read in Maxwell, and the electromagnetic force corresponding to each model to be analyzed is solved sequentially for the electromagnetic force parameter file to obtain an electromagnetic force data file. The Mechanical module 203 is configured to use Mechanical to read the model file in the SCDM and the electromagnetic force data file in the Maxwell respectively, and load the electromagnetic force in the electromagnetic force data file into the model to be analyzed in the model file according to the model name for structural simulation analysis.
