Paper Abstract

A finite element program such as NASTRAN provides displacements and rotations at grid points only. When ray tracing on a deformed surface, it is necessary to accurately determine the displacement and slope at all ray intersections which seldom occur at grid points. This paper describes a general purpose post-processing program to accurately interpolate over a model, using element shape functions. The user may specify a choice of linear interpolation or cubic interpolation for plate and shell models.
