OpenFOAM 1.5.x on Windows
For the latest version of our Windows patch for OpenFOAM visit "OpenFOAM 2.2.x on Windows".
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.
Are you looking for a GUI driven, integrated simulation environment for Windows, Linux, and Mac incorporating a selection of the RANS OpenFOAM solvers and various import/export filters?
The following steps are required to produce a native Windows version of OpenFOAM 1.5.x using a cross compiler:
- Configure, build, install and test a MinGW cross compiler for Windows running on Linux. I used the build-mingw script.
#include_next <float.h>to the end of
"lib/gcc/mingw32/4.2.3/include/float.h" and remove it from
"mingw32/include/float.h" to include the right "float.h".
- Install the OpenFOAM 1.5.x source (git Commit: 316c16a7cda8318061508cd4822037bf4685033c, Date: March 25, 2009) distribution on Linux
- Install the Third Party source pack and only compile the zlib library.
- Patch (using the Linux patch command) the OpenFOAM 1.5.x source distribution with our MinGW Windows modifications [last updated April 16, 2009 to v3].
- Copy wmkdep and dirToString from wmake/rules/linuxGcc to wmake/rules/linuxmingw32.
- Modify (or set environment variables) and source the etc/bashrc-mingw32 script to match your OpenFOAM 1.5.x source location.
- Build using Allwmake in the OpenFOAM-1.5.x directory on Linux.
- Transfer the OpenFOAM executables (applications/bin/linuxmingw32DPOpt/*.exe) and libraries (lib/linuxmingw32DPOpt/*.dll) to the Windows computer.
- Launch a Windows command prompt to run OpenFOAM.
Note that this latest version (v3) can now compile snappyHexMesh.
On the Windows computer ensure the following:
- The WM_PROJECT_DIR and USERNAME variables are set.
- The etc directory from the original source distribution is within the WM_PROJECT_DIR.
- The PATH variable is set to include the OpenFOAM executable and library locations.
With this method of building OpenFOAM for Windows the following features (there maybe more) are unavailable:
- job control scripts in bin (such as foamSolverSweeps)
The following applications and libraries are unlikely to build:
- metis and any dependents
You may need to copy foamFlex++ from a Linux OpenFOAM build to the MinGW build (applications/bin/linuxmingw32DPOpt).
