Effect of mesh deformation on the accuracy of 3D FEM electromagnetic analysis

In this paper, the accuracy of 3D FEM electromagnetic simulations in parametric analysis using mesh deformation techniques is discussed. Mesh deformation techniques allow one to preserve the mesh topology while the geometry is changed. It is shown that the application of mesh deformation can provide accurate simulation results even for very large deformations. On the other hand, it is also shown that the technique has to be used with special care, as in certain cases it may lead to less accurate results than the standard approach in which the mesh is regenerated from scratch.
