Some limitations remain for this new application :

Geometry and domain

  • Symmetries non supported.
  • Periodicities non supported.


  • The mesh should not be too refined in order to take advantage of this new methodology without overloading the solver which needs to inverse a full matrix.
  • Consequently, it is advised not to import the mesh from an external tool.

    Figure 1. On the left, a good mesh for the integral method. On the right, a good mesh for finite element method.
  • The elements of a mesh must be of the same type (only tetrahedrons or hexahedrons, but do not mix both).
  • No pyramids or prisms (the extrusive mesh is not recommended).


Available magnetic materials :
  • Linear isotropic
  • Isotropic analytic saturation (arctg, 2 coef.)
  • Isotropic analytic saturation + knee adjustment (arctg, 3 coef.)
  • Isotropic spline saturation
  • Linear magnet described by the Br module
  • Linear magnet described by cartesian vector Br
Regions :
  • Only magnetic non-conducting volume regions are available.
  • No face regions, line regions and point regions.
Non meshed magnetic sources :
  • No non-meshed saddle coils.
  • No non-meshed multi saddle coils.
  • No non-meshed coils in open path.

Parameters / Quantities

  • No sensors.
  • No Import/Export context.
  • In general, the use of import and export functionalities is not recommended.

  • No losses computation (iron losses & joule losses).
  • Available quantities : torque, force, magnetic flux and energy.
  • Only the isovalues and isolines of B and H are available.
  • B and H can be displayed on 2D and 3D grids in the air.
  • No Import/Export context
