SPH-flow Explorer: Bring design forward with earlier results

The SPH-flow solvers use the Smoothed Particle Hydrodynamics (SPH) method. This method looks at computational fluid dynamics in a new light. SPH-flow Explorer is made to simulate complex problems faster than ever before.

Fastest results to speed-up early-design exploration

SPH-flow Explorer: shortest time-to-results than ever


SPH-flow Explorer is a brand-new solver optimized to deliver results as fast as possible. It relies on finely tuned High-Performance Computing (HPC) capabilities, involving vectorization, MPI multi-CPU communications and, in a near future, OpenMP multi-threading and GPGPU technologies. SPH-flow Explorer can be 5 to 100 times faster than conventional Finite Volume (FV) solvers on applications that best fit with the SPH method, meaning that 1 week of computation may now shrink to few hours, with often better simulation results compared to FV on such applications.
