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.

In this paper the results of the PRACE SHAPE project “HPC Welding” are presented. During this project, a welding structure analysis with the parallel solvers of the LS-DYNA code was performed by Ingenieurbüro Tobias Loose on the Cray XC40 “Hazel Hen” at the High Performance Computing Center (HLRS) in Stuttgart. 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 results show that the implicit thermal and mechanical solver scales up to 48 cores depending on the particular test case due to unbalanced workload. The explicit mechanical solver was tested up to 4080 cores with significant scaling. As we know, it was the first time that a welding simulation with the LS-DYNA explicit solver was performed on 4080 cores.
