35 hours
Saved per test cycle of five impeller designs by simulating in parallel instead of bench testing
"I was the only CFD expert, and people from the department decided to include CFD as they found it very easy to use after a 1-hour explanation. This has broadened access to simulation within Tecnalia."
45%

SimScale supports laminar and turbulent flows, incompressible and compressible flows, multiphase flows using the volume of fluid (VoF) method, passive scalar and species transport, and conjugate heat transfer.
SimScale uses multiple solvers depending on the analysis type. For multiphase flow, it uses OpenFOAM's interFoam solver. For high-speed transient simulations, it offers a GPU-accelerated Lattice Boltzmann Method (LBM) solver.
The Lattice Boltzmann Method solver runs on multiple GPUs in parallel, delivering turnaround times 20–30 times shorter than standard CFD methods. Transient simulations that once took days now complete in hours.
SimScale supports several turbulence models including k-omega SST, k-epsilon, Smagorinsky, SST-DDES, and Hybrid SST-IDDES. The LBM solver in particular supports scale-resolving turbulence models for high-fidelity transient analysis.
Yes. SimScale includes conjugate heat transfer (CHT) and convective heat transfer analysis, enabling thermal modeling of conduction and convection together with the flow field in a single coupled simulation.
