As an integral part of the PRACE SHAPE project “HPC Welding” the parallel
solvers of LS-DYNA were used by Ingenieurbüro Tobias Loose to perform a
welding analysis on the Cray XC40 “Hazel Hen” at the High Performance Computing Center Stuttgart (HLRS).
A variety of test cases relevant for industrial applications have been set up with
DynaWeld, a welding and heat treatment pre-processor for LS-DYNA, and run on
different numbers of compute cores. The explicit mechanical solver was tested on
up to 4080 cores with significant scaling. As far as we know, it was the first time
that a welding simulation with the LS-DYNA explicit solver was executed on
4080 cores.
