Abstract

Motivated by the potential scalability challenge of unstructured FE simulation at scale, proposed is a FE approach that is free of the difficulty of mesh generation and is highly scalable in terms of pre- and post-processing. Its effectiveness is demonstrated through a structural analysis of 1.2. billion of DOFs, in which conforming mesh generation is prohibitively expensive and difficult.
