Jan. 21, 2013: Updated instructions for HPC Pack 2012 MS-MPI Redistributable Package

Here you'll find the instructions on how to create libmsmpi.a for the MinGW-w64 cross-compiler to link against for MPI applications, given the free MS-MPI Redistributable Package. Once configured with the msmpi library an MPI application can run in parallel on a multi-core Windows machine or in parallel on Microsoft Windows HPC Server (cluster). Using the technique described here a modified version of OpenFOAM for Windows was configured with native MPI support.

Most people are intuitively aware that the fluid flow of both gases and liquids is inherently transient (unsteady) by nature. As an example, just ponder the movement of leaves on a tree in a breeze or the flow of water from a tap. Less intuitive is that even a relatively steady flow in a wind tunnel has transient velocities that vary at scales and frequencies that our human senses are unable to discern. Such variations are known as turbulence. The treatment of turbulence in the Reynolds-Averaged Navier-Stokes (RANS) equations lies at the heart of most practical Computational Fluid Dynamics (CFD) approaches.

We have updated our Windows patch for OpenFOAM to match the latest OpenFOAM release (v1.5.x). Be warned - to build OpenFOAM for Windows with a cross compiler requires expert knowledge of Linux utilities and compilers.

OpenFOAM is a versatile open-source multi-physics simulation toolbox. It can simulate fluid flow (CFD), solid dynamics and electromagnetics (CEM). OpenFOAM was originally developed for Unix platforms, such as Linux, and until now there has not been a method for producing a native Windows version.
