Motor magnetothermal bidirectional coupling simulation method based on Fluent secondary development

The invention relates to the technical field of motor magnetothermal coupling simulation, in particular to a motor magnetothermal bidirectional coupling simulation method based on Fluent secondary development. In order to solve the problem of poor coupling between Maxwell simulation software and Fluent simulation software, the invention provides the magnetic-thermal bidirectional coupling simulation method for the motor based on Fluent secondary development. According to the technical scheme, a secondary development program UDF is written, the UDF is automatically loaded once before Fluent performs iteration each time, a motor coil temperature mean value is automatically updated after calculation each time, the new motor coil temperature mean value is recalculated in the UDF to obtain a new loss value, iteration is automatically performed for multiple times, and after a temperature field converges, a temperature field simulation result is obtained. According to the method, the problem of poor coupling of main
