Simple method to reduce computation time in planar airgap 3D FEM non-linear problems
Résumé
In the present work, an easily implementable method to reduce CPU time for some 3D FEM problems is presented. A translational displacement between two parts on both sides of a planar airgap is taken into account with a change of coordinates in the airgap region along the z-axis. To achieve this, formulation and post processing are slightly adapted. In this digest, the proposed method is applied to an academic problem. Results are compared to a usual method. Time saving, ease of implementation and precision on prelimary results are really encouraging with a strong reduction of CPU time keeping a low relative deviation. The method could be easily applied to any configurations with planar airgap as MAGLEV, axial motor or levitation device.
