Abstract

In developing movies of three-dimensional, finite element simulations of nonlinear transient response, algorithms for identifying interior nodes and edges in finite element meshes are very useful. In this paper an extremely simple and fast algorithm, in which the interior nodes are identified by assembling the normals to all surfaces of the model according to the usual finite element assembly procedure, is described. Comparison with a sort-search algorithm shows a tenfold reduction in running time; running time is always a linear function of the number of nodes or elements. Some examples of applications are given.
