OpenCruncher is a compressible computational fluid dynamics (CFD) flow solver for Large Eddy Simulations (LES) running on CPUs as well as on GPUs. It is an open-source code, distributed freely under the terms of the GNU Public License (GPL). The design goal is to provide a fast solver for transient flows in complex geometries.

Build and run the code, see the screencasts, the validation examples or the reference manual to get familiar with OpenCruncher.
