Abstract

The invention provides a realization method based on unification of a heat-force-electromagnetic field network. The realization method comprises: step 1: performing finite element mesh dividing on a model by using thermal analysis software, so as to obtain a thermal coupling grid of the model; step 2: converting a file format of the thermal coupling grid of the model into a file format which can be identified by electromagnetic software; and step 3: inputting the converted thermal coupling grid file to the electromagnetic software, and performing analysis to obtain thermal field distribution data of the model, so as to obtain an electromagnetic data distribution pattern that is based on temperature field distribution and deformation. According to the realization method provided by the invention, the heat-force-electromagnetic field network is unified; a design scheme can be simulated and verified more accurately and more effectively; system performance is ensured; and a design risk is reduced.

technical field [0001] The invention relates to the field of thermodynamic and electromagnetic analysis, in particular to a realization method based on a unified thermal-mechanical-electromagnetic field network. Background technique [0002] At present, electromagnetic software for solving electromagnetic induced current and voltage, such as ANSOFT; software for calculating fluid and thermal deformation, such as MP; they are all based on different network division processing models, the former adopts mostly hexahedral grid processing models, and the latter Models are processed using mostly triangular meshes. Therefore, the two cannot achieve a unified grid and file format, which means that the one-to-one correspondence between the distribution position of the thermal field and the distribution position of the electromagnetic field cannot be realized.

[0003] Since the problem solved and analyzed by the thermal analysis software is based on the tetrahedral model composed of triangular meshes, the structural size and appearance of the model can be described more accurately by using this mesh, and the calculation of thermal radiation can be realized more accurately. However, in the electromagnetic field Under radiation, the model diverges and does not converge, resulting in a very long number of calculation iterations, requiring high-performance computer processing, which will inevitably increase hardware costs

Electromagnetic analysis software usually adopts a hexahedral grid-based processing model, which has high convergence of electromagnetic field radiation, a small amount of calculation, and high efficiency. However, it cannot describe the ejection caused by irregular geometric edge effects in the thermal analysis model, and then Inaccurate thermal radiation calculation
