The Development and Application of Massively Parallel Solid Mechanics Codes
Computational physicists at Sandia National Laboratories have moved the Eulerian CTH code, and the arbitrary-Lagrangian-Eulerian ALEGRA code to distributed memory parallel computers. CTH is a three-dimensional solid mechanics code used for large-deformation, shock analysis [1,2]. ALEGRA is a three-dimensional arbitrary-Lagrangian-Eulerian code solid-mechanics code used for coupled large-deformation, shock and structural mechanics problems . This paper discusses our experiences moving the codes to parallel computers, the algorithms we used and our experiences running the codes.
