An implementation of a mesh adaption procedure for 2D “time-harmonic” solution, based on “h-refinement” criteria, using as error estimate the “local field error” approach, is presented. The error estimate is based on the solution, on an “element-by-element” basis, of an adjoint error problem cast in terms of magnetic induction. The “self-adapting” meshing procedure is iterative and is composed of a series of modules for the various functions. The electromagnetic problem is solved using the Esprit project MIDAS-2D “frequency domain” FEM solver. Some test cases at various frequencies are presented and results are discussed
