Returned solution has not converged.

Please login with a confirmed email address before reporting spam

Hello All,

When I try to use 3D-AC/DC Module-Magnetostatics(emqa) to get the inductance of a three turns copper coil with magnetic materials covered, I will always meet the problem:
Failed to find a solution:
Divergence of the linear iterations.
Returned solution has not converged.

I have set the geometry well, so could it be the problem of mesh? Or is it because the geometry is too complicated?

If anyone happens to know how to solve this problem, plz tell me how to fix it.

Thank you very mcuh.

Try to change the tolerance in your solver configuration. Increase it a little bit.
You can also try to use a corser mesh

Thanks for your answer.

But coarser mesh will result in the failure of mesh. Is there any better other ways to find the inductance of the coil shape inductors?
