HemeLB is a highly scalable, 3D blood flow solver capable of generating high-resolution simulations of blood flow through human-scale vasculatures. Post-processing such simulations is a significant challenge, particularly due to the volume of data generated. We have utilized Intel OSPRay Studio to visualize generated data timeseries directly on the production machine — SuperMUC-NG at LRZ. We use a custom input plugin to efficiently map the simulation data whilst eliminating complex pre-processing. This allows the full domain simulated by HemeLB to be quickly observed by users for assessment.
