Mesh adaptation in finite element analysis of 2D steady state time harmonic eddy current problems

A local error estimation and adaptive meshing method developed by the authors for finite element analysis of 2D electrostatic and magnetostatic problems is now extended to 2D steady state time harmonic quasistatic eddy current problems. Local error estimation is based on the approximate solution of an independent differential problem in each triangular element. Mesh refinement is carried out by adding nodes in the centroids of selected elements and then applying the Delaunay algorithm.
