Accelerate OpenFOAM with SpeedIT 2.1

May 24th, 2012

SpeedIT provides a set of accelerated solvers for sparse linear systems of equations. The library supports C/C++ and Fortran, and it can be used with OpenFOAM to accelerate CFD simulations. SpeedIT 2.1 contains two new preconditioners:

• Algebraic Multigrid with Smoothed Aggregation (AMG)
• Approximate Inverse (AINV)

OpenFOAM simulations on the GPU can be up to 3.5x faster compared to CG and DIC/DILU preconditioners on the CPU and up to 1.6x faster if you run GAMG.

See the SpeedIT website and blog for more details.
