Abstract

A hybrid finite-element-boundary integral method using an electric variational formulation (3-D code Trifou-e) is presented. Whitney´s edge elements are used in conducting regions and the boundary element technique is used for exterior regions. The electric field is taken as the state variable for both of the regions, whether modeled by the finite-element or boundary-integral techniques, so that the problem of multiply connected regions can be treated in a convenient way
