Accelerating Explicit FEM Shock & Blast Simulations

Abstract:
Explicit finite element codes are widely used to simulate the response of structures and mechanical equipment subjected to shock, blast and wave propagation phenomena. High resolution models require run times ranging from a few seconds to a few months are common and hence the payoff from GPU acceleration is tremendous. We describe the acceleration of our commercial finite element code NLFLEX using CUDA. We developed GPU kernels in CUDA based on our production code NLFLEX, for linear elasticity, explosives, elasto-plasticity and large deformation elasticity. We attained order of magnitude (10X) acceleration in single precision and approximately (5X) in double precision mode.
