How can I improve cogging torque computation with Flux 2D?

In the case of low cogging torque values, it can be necessary to modify the mesh of the region corresponding to the exterior air gap layer. The purpose is to mesh this air gap using regular mapped mesh.

The computation step has also to be adapted. The purpose is to get an elementary move equal to the length of the edge of a quadrangular mesh element.
