Hello Guys. This is my first post so please bear up with me.

I am trying to make a model that can model the electromagnetic field lines and force field strength for a three phase system. I have made the models, but the system will for some reason not converge.

When i try to converge, I get following message: Feature: Stationary Solver 2 (sol1/s2) Undefined value found. - Detail: NaN or Inf found when solving linear system using MUMPS.

I do not know what i am doing wrong, since im quite new at this.

Does anyone have a clue?

Cagribey,

Set air conductivity to some non-zero small value, say 1 S/m, and solver will converge. This is so called conductivity scaling effect.

Sergei

Hello Sergei, thanks for the reply. It feels like that value can be 0 in 2d, and not 3d. do you know why, btw it worked
