Blood Flow through a Microaneurysm
SessionArt of HPC Display
DescriptionWe used the Coreform Cubit software to create an Exodus-II tri-mesh with 11,196 points for the blood vessel walls. Red blood cells are placed randomly within the mesh bounds, and then the algorithm from RBC3D, a spectral boundary integral solver for cell-scale flows, initiates Stokes flow through the vessel. This algorithm is parallelized via MPI, and we had to use 192 CPU cores for eight hours to run this simulation to 10,000 timesteps. To visualize the simulation data, we used Kitware's ParaView software. Then, we used two NVIDIA RTX 6000 GPUs to run the OSPRay path tracer algorithm from ParaView's ray-tracing tools. Georgia Tech's PACE Phoenix cluster provided access to CPU and GPU nodes under Spencer Bryngelson's allocation. The ray-tracing step took 16 hours on these nodes. Finally, we combined images of the simulation from each timestep into a video using FFmpeg.
