چکیده

We have constructed extensions to the capabilities of the dynamic Lagrangian solid mechanics code EPIC ([10, 11]) to enable basic h-adaptivity on a limited range of problems. The indicators for adaptive refinement include a feature indicator based on relative velocity, a flux jump indicator, hybrid indicators and a stress recovery indicator. We use this capability to test different measures of solution quality and adaptive refinement schemes on a benchmark Taylor anvil test problem.

| The MPI 1:1 de nition includes routines for nonblocking point-to-point communication that are intended to support the overlap of communication with computation. We describe two experiments that test the ability of MPI implementations to actually perform this overlap. One experiment tests synchronization overlap, and the other tests data-transfer overlap. We give results for vendorsupplied MPI...
