A Spaceclaim®-embedded Multiphysics Simulation Package

By

MONTREAL (September 25, 2014) – EMWorks Inc. announces the launch of its multi-physics simulation package SimClaim which is fully embedded in Ansys SpaceClaim®, formerly SpaceClaim, Engineer®.  Based on the powerful finite element method, SimClaim brings the company’s proven simulation technology to the widest base of mechanical, electrical and electromechanical designers seeking to validate and optimize their electrical, thermal, and structural designs all within the SpaceClaim environment. “We are pleased to have partnered with SpaceClaim to bring this all important multi-physics simulation technology to the SpaceClaim user community. The support we received from SpaceClaim over the last couple of years has been instrumental in accomplishing this important milestone for our company” said Dr. Ammar Kouki, Vice-President of EMWorks. He added “Ansys SpaceClaim®, is an extremely powerful 3D direct modeling software package that eliminates CAD worries for designers. Direct modeling is dramatically different from the traditional CAD software because it allows the user to directly access the model without even knowing its history. SimClaim leverages this power to enable designers and CAE specialists to carry out conceptual analysis inside SpaceClaim in record time without needing to be CAD experts. CAD experts on the other hand, will find that the SpaceClaim-SimClaim combination is hard to beat when it comes to design validation through simulation given the speed and the highly efficient workflow that this combination offers.”

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.
