A finite element code for solving the regularized Maxwell equations in engineering applications

This work presents a nodal-based finite element code in frequency domain called ERMES. The novelty of this computational tool rest on the formulation behind it. ERMES (emphElectric emphRegularized emphMaxwell emphEquations with emphSingularities) is the C implementation of a simplified version of the weighted regularized Maxwell equation method citeWRME-Costabel,SWRME-ROtin. This finite element formulation has the advantage of producing well-conditioned matrices citeNodalEdgePS,ERMES-SAR and the capacity of solving problems in the low (quasi-static) and high frequency regimens. As a consequence of this versatility, ERMES has been applied successfully to microwave engineering citeSWRME-ROtin, specific absorption rate computations citeERMES-SAR,ERMES-SARRFID, electromagnetic compatibility citeERMES-Zt and electromagnetic metal forming citeERMES-EMF. In this work we will describe the main features of ERMES and its formulation (peculiarities, comparative performance with edge-based formulations,etc...). Also, we will show how to use this numerical tool for computing electromagnetic fields in a wide variety of engineering applications. The version of ERMES described in this work (executable files, documentations and source code) is freely available under request to the author. beginthebibliography0 bibitemWRME-Costabel M.
