The solver doesn finish running. Whats going on?
You probably didn’t apply any boundary conditions to the problem. Although the solver will sometimes find a solution in cases in which boundary conditions haven’t been specified (e.g. in cases with only permanent magnets), it’s not guaranteed to finish unless you have defined boundary conditions on the edges of your problem. The easiest type of boundary condition is the “Prescribed A” boundary condition type. Set all of the parameters to zero. Apply this boundary condition to all the outside edges of your solution region.
