EM Programmer's Notebook-some finite-element preprocessing algorithms for electromagnetic scattering

摘要

All finite-element mesh-generation packages output a so-called universal file which, as a minimum, contains a list of the node coordinates, a table of the nodes which form each element, and a list of the materials filling the element. Algorithms that make use of this information to generate additional information or tables, which are typically required in any electromagnetic analysis code, are given. The given code fragments are in C to avoid explicit dimensioning of arrays and facilitate the execution of recursive routines.
