GPU-Based CFD Solver Using Lattice Boltzmann Method

Transient simulations have historically required a high investment both in time and money to provide accurate results. This GPU-based solver uses the lattice Boltzmann method (LBM) to tackle this problem by pairing high accuracy with unparalleled speed and is accessible via the cloud with SimScale’s CFD analysis software.

We partnered with Numeric Systems GmbH to develop this innovative feature through their tool Pacefish®. We have reduced running times for transient simulations from weeks and days to hours and minutes. Its ability to run on multiple GPUs in parallel enables turnaround times that are 20-30 times shorter than standard methods. Moreover, Pacefish® supports several turbulence modeling types such as Smagorinsky, SST-DDES, Hybrid SST-IDDES, and k-omega SST making it unique among other LBM solvers.
