Time-harmonic mesh adaption with error estimate based on the ''local field error'' approach

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.
