A direct solver (PARDISO) is used instead of the default iterative solver. In order to solve a Magnetic Fields problem with a direct solver it is necessary to apply the Gauge Fixing for A-Field feature.

|
The discretization order for the magnetic vector potential A is set to use Linear elements. The discretization order of the Jiles-Atherton auxiliary dependent variables is then automatically set to zero.
