Meshing air gaps
Today’s tip is about meshing air gaps.
Air gaps are integral parts of electrical machines. However, they can represent a real challenge even for the most advanced finite element meshers. To facilitate meshing air gaps in EMS, we recommend that you construct a separate part or body for the air gap in SolidWorks or Inventor. Then you apply a tight mesh control on the air gap parts or bodies, which should be much smaller that the mesh size in the surrounding air where the mesh is usually coarse because the field tends to decay away from the device. Hence, you can easily mesh the air gaps and achieve a good accuracy without causing a large number of mesh elements.
