*Discontinued Sept. 3, 2013: OpenFlow command-line binaries are no longer available for purchase*

OpenFlow is a native Windows (without emulation) port of OpenFOAM®¹ 2.1.x. OpenFOAM is a versatile multi-physics, open source², simulation toolbox - renowned for its wide support of numerous Computational Fluid Dynamics (CFD) methods.

OpenFlow on Windows

You can purchase a complete set of OpenFOAM solvers and utilities as command-line applications for Windows 64-bit with native parallel capability, packaged within a convenient Windows installation wizard. This is provided as a convenience to those who don't have the resources to modify and cross compile³ the OpenFOAM source. The license is not time limited, i.e., it extends indefinitely for the release you purchase.

Purchase with confidence with our 30 day money-back guarantee. Once your payment clears you will receive email instructions on how to download the OpenFlow installer.

Support

A dedicated OpenFOAM discussion forum is hosted at CFD Online.

Windows HPC Server 2012

job submit example on Windows HPC Server 2012 for simpleFoam:

job submit /jobname:simpleFoam-jobName /name:simpleFoam-taskName /numprocessors:16 /stdout:\\CRAY01\<of-case>\stdout.txt /stderr:\\CRAY01\<of-case>\stderr.txt mpiexec -env WM_PROJECT_DIR \\CRAY01\OpenFlow-5 -env MPI_BUFFER_SIZE 20000000 -env USERNAME openfoam -env PATH \\CRAY01\OpenFlow-5\platforms\win\bin;\\CRAY01\OpenFlow-5\platforms\win\bin\mpi simpleFoam -parallel -case \\CRAY01\<of-case>\pitzDaily

Note you need to share both the case (\\CRAY01\<of-case> - arbitrary name of your choosing) and application directories (\\CRAY01\OpenFlow-5) so all nodes on the cluster can access them.

Experimental GPU Linear Solvers

For details see "GPU v0.2 Linear Solver Library for OpenFOAM".

To enable set the additional path variable:
set PATH=C:\Program Files\OpenFlow-5\platforms\win\bin\cuda;%PATH%

System Requirements

• Windows XP, Windows Vista, Windows 7, or Windows 8
• 64-bit only
• 430 MB free disk space
• [optional] Parallel requires either:
  • Free Microsoft HPC Pack 2012 MS-MPI Redistributable Package - included in OpenFlow installer for a multi-core computer
  • Microsoft Windows HPC Server 2012 for a cluster
• [optional] NVIDIA CUDA-enabled device for GPU Linear Solvers

Features

Our OpenFlow distribution has the following features:

• Single precision - permits larger problems compared to double precision within the same memory constraints
• No libccmio
• No libcgns
• No UNIX job control scripts
• No ParaView - though it is freely available
