Hi friend
I have a basic question!
what is the meaning of :
$WM_PROJECT_DIR
is it just for openFoam or this is a general command in linux?
why do we use $ in the start point of some addresses?
what is under lines between those words?
and finally, what is WM_PROJECT_DIR?

thanks

Hi A.Min,

I suggest you to take a first look in this link before start using OpenFOAM: http://openfoamwiki.net/index.php/In...with_the_Shell

Regarding your question, when you are working with the shell in the Linux terminal, any $ is a environment variable. If you want to which is the return of this variable, you can use the command

echo $WM_PROJECT_DIR

and it should return, for this specific environment variable, a path to the installation directory of the current OpenFOAM sourced. This is an OpenFOAM environment variable. You should not have anything returned with the command above if you didn't source OpenFOAM yet.

The " _ " between the words is only to separate it instead of using spaces (because you can't).

Other OpenFOAM environment variables are $FOAM_RUN, $WM_PROJECT_USER_DIR, $FOAM_APP, $FOAM_SRC, ..

Good luck !
