Abstract

When performing the analysis of electromechanical transient problems with movement, it is needed to take into account the air gap deformation with time. A new remeshing procedure is proposed. It is based on node displacements coupled to a Delaunay algorithm. The node movement is described using bubbles in association with a physical model. The procedure generates high-quality meshes.
