چکیده

This paper focusses on recent developments and on-going research related to parallel and distributed approaches for crashworthiness simulation, using the PAM-CRASH code from ESI as an example. The developments described here relate directly to the take-up in the automotive industry of the latest High Performance Computing (HPC) technology, since crash and safety analysis is well established in the automotive design process.

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver

In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
