Hi!

This is not a really a bug, but I couldn't think of fitting place to post this.

One of the cool features of OF is that Debug/Opt, SP/DP and different MPI-implementations happily reside in the same directory tree side-by-side and can be chosen by the init-scripts. The downside is that one either has to edit the initiscripts and re-source them or has to work with symbolic links for different versions.

What I would propose is (I'm doing this for bashrc) is to add this function to .OpenFOAM-1.4.1/bashrc

SetDefault() {
TMP_DEFAULT=`eval echo \${${1}_DEFAULT}`
if [ "$TMP_DEFAULT" ]; then
eval "export $1=$TMP_DEFAULT"
else
eval "export $1=$2"
fi
}

and replace assignments like this

export WM_COMPILE_OPTION=Opt

with this

SetDefault WM_COMPILE_OPTION Opt

(I think this makes sense for WM_PRECISION_OPTION, WM_COMPILE_OPTION and WM_MPLIB)

Now if, for instance, one wants to switch one shell to the profiled, single-precision version with LAM he issues the commands

export WM_PRECISION_OPTION_DEFAULT=SP
export WM_COMPILE_OPTION=Prof
export WM_MPLIB=LAM
. .OpenFOAM-1.4.1/bashrc

The advantage of not editing the init-file would be that unpleasant surprises (starting a job with the wrong precision for instance) for other users living from that installation would be avoided
