Nonsymmetric matrix

Please login with a confirmed email address before reporting spam

In a simulation I am running, two coils wound on separate cores separated by an air gap are connected in series (Coils 1 and 3 are in series, and Coils 2 and 4 in series as well). When I run, I see the following in my log with almost no progress:

Nonsymmetric matrix found. Scales for dependent variables: Magnetic vector potential (comp1.A): 1.7e-05 Divergence condition variable (comp1.mf.psi): 1

The physics I use is similar to that in the ecore_transformer tutorial.
