DYNA3D is an explicit finite-element program for analyzing the transient dynamic response of three-dimensional solids and structures. ParaDyn is a message-passing parallel version of DYNA3D. Typical problems use very irregular, unstructured meshes. The performance characteristics of any problem are very dependent on the mixture of element types and algorithms used for the physical model.
The problem analyzed here ran on 32 thin nodes of an IBM SP2 (blue.pacific.llnl.gov). It had 1046797 nodal points which formed 1019384 hexes. The full text of the report is contained in DYNA3D Characterization.
