We have updated our Windows patch for the latest OpenFOAM® release (v1.7.x). As with the previous patch version this also supports 64-bit compilation using the MinGW-w64 cross-compiler and parallel computation using the native Windows MPI implementation provided by the free Microsoft HPC SDK and also available on Microsoft Windows HPC Server 2008 for clusters.
The latest version of our Windows patch for OpenFOAM® 1.6.x now supports 64-bit compilation using the MinGW-w64 cross-compiler and parallel computation using the native Windows MPI implementation provided by the free Microsoft HPC SDK and also available on Microsoft Windows HPC Server 2008 for clusters. Be warned, as always, that to build OpenFOAM for Windows with a cross-compiler requires expert knowledge of Windows and Linux utilities and compilers.
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.
We have updated our Windows patch for OpenFOAM to match the latest OpenFOAM release (v1.6.x). Be warned - to build OpenFOAM for Windows with a cross compiler requires expert knowledge of Linux utilities and compilers.
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.

Caedium: An Interactive Simulation Environment for OpenFOAM
Richard Smith, Symscape
Caedium is a CAE system designed to support CFD and other forms of analysis. The latest addition to the Caedium modular architecture is the RANS Flow add-on, which provides an interactive environment for a selection of RANS OpenFOAM solvers.
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.
Dimensionless (or non-dimensional) numbers, such as the Reynolds number and Mach number, are a general concept (extensively used within fluid dynamics) to allow comparison between similar flow physics carried out at different scales and with different fluid properties.

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.
If you are one of the lucky few that creates native geometry within a standalone Computer-Aided Engineering (CAE) analysis tool or within a single Computer-Aided Design (CAD) system with embedded CAE analysis tools, then stop reading now. Just a moment though, even if you have embedded CAE tools within your CAD system, but you import geometry for analysis you will still face geometry exchange challenges.
