Visualization of high resolution, three-dimensional, nonlinear finite element analyses

Abstract

A two-pass surface extraction algorithm for adaptive finite-element meshes is presented in the context of a visualization study for a particle impact and a turbine-blade containment problem. The direct use of finite-element data structures for the computation of external surfaces, surface normals, and derived physical qualities is discussed. An overview of the in-betweening which accounts for rigid body dynamics effects is presented, with a brief discussion of a direct-to-videodisk animation strategy.<>
