Hello,

i would like to use some VHF ferrite absorber material in my CST Studio Suite simulation. The problem is by creating a material with magnetic loss the number of meshcells are increasing so much that i couldn't even start the simulation. I'am using the timedomain T solver at 0 - 500 MHz. So my first question is, why does CST need so much meshcells for simulating magnetic losses?

To reduce the number of meshcells or to force CST to use not so much meshcells, i defined a local mesh propertie for the absorber and deactivated the "Material based refinement". Hereby the meshcells are reduced to a good number. So my second question is, can i simulate the absorber material this way and get useful results? Is the inaccuracy of the simulation result to big?

The material i would like to simulate is found here: https://hollandshielding.com/VHF-ferrite-absorber-tiles

Thanks!!!
