Hello, I am new in feko and I would like to simulate a transformer in toroidal form on which is wound two coils (primary and secondary) in order to determine the magnetic field throughout the space. I would like to do it in magnetostatics. But I have modeled the toroidal geometry which has dimensions of the order of the centimeter. I put a very low frequency (1Hz) as I work in magnetostatic. But I have conditioning problems when solving. When I put higher frequencies, the mesh becomes gigantic and takes a lot of time? I would like to know if it is possible to make such simulations with feko? Thanks for help.
Hello, I can't solve the problem with model prepared in HyperMesh and exported to Flux. Model consists of two cylindrical coils on yoke, a solid conductor below them and the surrounding tetrameshed air. Analysis is set to magnetostatic. There is no non-linearity in any material Chesk physics doesn't give any error. Whenever I start to solve problem, Flux gives: "End of physical check. 12:03:00 9 sec.
