Software for computer simulation of multiphysics processes in electromagnets and actuators of vacuum switching devices taking into account contact interaction of structural elements. Part 1: general overview; features of in-house codes

Abstract

For computer modeling of multiphysics processes in complex modern technical objects, for example, in actuators and electromagnets of vacuum switching devices, it is necessary to use modern application software aimed at solving the entire spectrum of the specified problems or one or another "subset" of them. Complexes of applied programs must implement modern mathematical models and corresponding effective numerical algorithms, as well as have convenient interfaces both for the preparation and input of initial information (preprocessor), and for the output and analysis of the obtained results (postprocessor). The presence of the most "user-friendly" preprocessor and postprocessor is extremely important, considering the significant complexity of the processes being modeled, as well as the structures considered by the researcher and/or design engineer. It is of interest to carry out a comparative analysis of specific software products, with the aim of choosing a "tool" for the implementation of a complex of computational studies (computer modeling of multiphysics processes in the structural elements of medium and high voltage vacuum switching devices, taking into account contact phenomena), specified above. The article considers the criteria by which a reasonable choice of software can be made, which will be directly used for mathematical modeling of technical objects and processes under consideration.
