Re: [femm] Non linear Anysotropic analysis
Daniele,
Here is a simple example for you.
The m-27 steel on the left is isotropic.
The m-19 has the Uy property changed by one
decimal point to 441.6 from 4416.
Notice the difference in the flux patterns?
Good luck,
Dave Squires

Hello,
I' writing from Italy, and my problem is the following... I have to
perform a non-linear simulation with Femm, but the material in use is
not isotropic (I think Femm doesn't allow this)...is there anyone
that knows some "trick" about it? (for example, to assign a
lamination that "simulate" the anysotropic behaviour)...
If in any case this analysis can't run with current version of femm,
I hope it will become developed in future...
Best regards,
Daniele
