User-installable modules (and EasyConfigs)

Install with the EasyBuild-user module:

eb <easyconfig> -r

To access module help after installation and get reminded for which stacks and partitions the module is installed, use module spider OpenFOAM/<version>.

EasyConfig:

Technical documentation

This easyconfig is based on the public CSCS version using Binary easyblock.

Rewritten to use recent configuration layers built-in the OpenFOAM.

OpenFOAM in two flavours (branches) from: openfoam.com (YYMM release numbering) and openfoam.org (N release numbering).

Build Issues

openfoam.com

Subsequent compilation with Allwmake will now run largely without any problems, except that the components linking against CGAL (foamyMesh and surfaceBooleanFeatures) will also try to link against a nonexistent mpfr library. As a workaround, the link-dependency can be removed in wmake/rules/General/CGAL :

CGAL_LIBS = \
    -L$(BOOST_ARCH_PATH)/lib \
    -L$(BOOST_ARCH_PATH)/lib$(WM_COMPILER_LIB_ARCH) \
    -L$(CGAL_ARCH_PATH)/lib \
    -L$(CGAL_ARCH_PATH)/lib$(WM_COMPILER_LIB_ARCH) \
    -lCGAL

Fixed overwriting wmake/rules/General/cgal with wmake/rules/General/cgal-no-mpfr

openfoam.org

Missing linux64Cray rules files are in the patch file consisting options from Esko Järvinen (CSC).

Notes on CPE

This easyconfig produces linux64Cray platform binaries using Cray compiler option which is in fact CPE GNU.

Issues with OpenFOAM v2106 and GCC 11

Linking fails for OpenFOAM v2106 and GCC 11. We run into issue 2147

The fix proposed there is to compile with -D_GLIBCXX_USE_CXX11_ABI=0. However, as OpenFOAM does not honour the pretty standard CXXFLAGS environment variable, the only solution is to inject this option using FOAM_EXTRA_CXXFLAGS and this has to be done after calling the etc/bashrc script as that script unsets the variable to avoid accidentally using settings from a previous compile in the same shell.

OpenFoam v2212

Trivial port of the EasyConfig

OpenFOAM v2312

For now a trivial port of the 2212 EasyConfig
