Algorithms

Fast

The fast algorithm (also weak coupling, one way coupling) calculates electromagnetic sources once and apply them to the thermal model. Reverse interaction (change of electromagnetic properties due to heating) is not taken into account.

The fast algorithm gives good results if the time step is small compared to the heating rate.

Accurate

The accurate algorithm uses two-way coupling - electromagnetic sources are recalculated according to the temperature field until convergence is reached. The accurate algorithm gives very precise results and is important for highly nonlinear problems.

Auto

Automatic algorithm switches between Fast and Accurate according to user input:

• Fast if materials have constant permeability and electrical conductivity
• Accurate if materials have nonlinear magnetic properties (B-H model and/or temperature dependence) and temperature dependent electrical conductivity
