SpeedIT Flow™ is one of the fastest Computational Fluid Dynamics (CFD) implicit single-phase flow solver currently available. In contrary to other solutions a Semi-Implicit Method for Pressure Linked Equations (SIMPLE) and the Pressure Implicit with Operator Splitting (PISO) algorithms have been completely implemented on graphics processing unit (GPU). Based on the Finite Volume method.
SpeedIT Flow™ robust solver technology empowers users by providing accuracy in double precision on fully unstructured meshes up to 11 million cells. Our implementation was validated on standard steady and unsteady industry-relevant problems with RANS turbulence model. Its computational efficiency has been evaluated against the fastest possible CPU runs using OpenFOAM*. The results show that a server-class GPU outperforms a server-class dual-socket multi-core CPU system running essentially the same algorithm by a factor of 3.
