OpenFoam

Version 1.7.1

Needs to be built with gcc 4.4.4 or newer. Gcc 4.4.4, in turn, requires a bunch of stuff so we have the following (in the order in which they should be built).

gmp-5.0.1

./configure --prefix=/apps/openfoam/tools
make -j 4
make install

ppl-0.10.2

There is an error in the configure script due to a change in GMP fixed as below.

OpenFOAM: Build Notes

Be wary of changing their default directory structure. Although it appears easy to do in the "etc/bashrc" file, there are places in the wmake build system that seem to be hardwired for the "$WM_PROJECT-$WM_PROJECT_VERSION" structure and parts of the build will fail.
When building the support software (ppl, gmp, etc.), it is probably best to specify "--libdir=<prefix>/lib64" to the configure script. Gcc will build both 32 and 64 bit libraries so you will end up with a mix of 32 and 64-bit libraries in your <prefix>/lib dir if you aren't specific.
The default OpenFOAM installation denies access to most of the files and directories to "other". If others are to use the install, the permissions on many files have to be changed from 750 -> 755, 740 -> 744, and 640 -> 644.

ParaView (3.8.0)

Rather than building ParaView and all its associated dependencies from source, I did the following.

cd /var/tmp
wget http://www.paraview.org/files/v3.8/ParaView-3.8.1-Linux-x86_64.tar.gz
tar xvf ParaView-3.8.1-Linux-x86_64.tar.gz
cd /apps/OpenFOAM/ThirdParty-1.7.1/platforms/linux64Gcc
mkdir paraview-3.8.1
ln -s paraview-3.8.1 paraview-3.8.0
paraview-3.8.1
(cd /var/tmp/ParaView-3.8.1-Linux-x86_64/; tar cf - *) | tar xvf -

This just puts the downloaded version of ParaView (and all the support libraries) in the location expected by OpenFOAM - no need to update PATH and LD_LIBRARY_PATH with new entries for paraview. They are already included in the paths set by the OpenFOAM bashrc file.

Yes, there is a minor version difference but as long as it works, we won't quibble over the details.
