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 estimat e the ''Local Field Error'' approach, is presented. The error estimate is based on the solution, on an ''element-by-element'' basis, of an a djoint error problem cast in terms of magnetic induction, The ''self-a dapting'' meshing procedure is iterative and is composed of a series o f modules for the various functions, The electromagnetic problem is so lved using the Esprit project MIDAS-2D ''frequency domain'' FEM solver . Some test cases at various frequencies are presented and results are discussed.
