The benefits of nodal and edge elements coupling for discretizing global constraints in dual magnetodynamic formulations

摘要

The treatment of massive and stranded inductors is studied in the frame of dual magnetodynamic finite element h- and a-formulations. On both sides, nodal and edge finite elements are used and source fields are defined when needed as mathematical tools to be used directly in each formulation to lead to circuit relations for inductors. Simplified expressions of source fields are proposed.
