A finite-element mesh adaptation process is described for the analysis of t
wo-dimensional steady-state time-harmonic skin effect problems, An integro-
differential formulation in terms of the magnetic vector potential is used
to solve the basic finite-element problem. ri local error problem is set up
and solved to estimate the solution error on a per-element basis. Mesh ref
inement is accomplished by inserting new nodes in the centre of the element
s or of their sides and by applying the Delaunay triangulation algorithm.
