The scalability performance of Altair Radioss software when running in parallel with up to 1152 cores, using mono and multi-domain techniques, was assessed for a large airplane-ditching model. Within the range of cores tested for the multi-domain (72 to 288 cores), the overall efficiency of the multi-domain simulations was significantly higher than the monodomain, taking almost a third of the time to complete the simulation when compared to the monodomain model for 72 cores. Both techniques have shown excellent scalability, with high scaling efficiency and with outstanding reliability of the results.
