Zirka hysteresis model
Posted: 24 Jan 2024, 09:16
Hi all,
I was wondering if anyone with some experience with Zirka materials can let me know if this is a bug or I am missing something. This is a simple case of a coil and a piece of metal (Low frequency, no eddy currents, metal conductivity =0). Case with single BH curve works as expected, but when I switch to a Zirka material things get weird. Other than the overall BH curve not following the input curve, the evolution of the BH curve also seems weird. I used values from the elmer tests. I could trace some of the input parameters to the Zirka paper but others were not that easy to find. For instance, I am not sure why we need to specify a relative permeability (it crashes if it is not included)
