An FEM Code For Electrical Engineering Research:ELFIN

This paper discusses the basic philosophy and design guidelines of the ELFIN code for electromagnetic CAD research. ELFIN is basically a finite-element code, conceived as a sort of numerical analysis laboratory, expressly tuned to research purposes, where innovative procedures can be easily implemented and tested. The main features of the code are N-dimensional (ID, 2D and 3D) parameterization of procedures, wide application to PDE, IE and IDE problems, and easy treatment of coupled problems, mixed approaches and generalized iterative procedures. Examples of application to 2D and 3D electromagnetic CAD research are given.
