Fluid Dynamic Simulations of "Euplectella aspergillum" Sponge
, Cineca
We present our experience in simulating the flow around a silica-based sponge, the "Euplectella Aspergillum," using a TOP500 machine equipped with NVIDIA GPUs. A Lattice Boltzmann Method (LBM)-based code was used to explore fluid dynamical features of this complex structure. We'll present some physical results, together with details of code implementations and performance figures (up to about 4,000 V100 GPU) for our MPI+OpenACC LBM code.
