Geometric interpretation of finite‐dimensional eddy‐current formulations

This paper gives an explicit geometric interpretation of finite element formulations of the eddy‐current problem. The paper shows, step‐by‐step how the eddy‐current problem can be implemented in a finite element kind of software system exploiting familiar geometric ideas such as lengths of edges, areas of faces, volumes of tetrahedra, and the mutual interconnections between the simplices of a mesh. The approach is a specific case of the so‐called geometric techniques.
