Hello,

I am working on HPC clusters and don't have permission to install new solvers at $FOAM_APPBIN.
When I tried to change Make/files
EXE = $(FOAM_USER_APPBIN)/mySolver

it gives an error that the directory does not exist. So, where and how do I define the user bin directory in my home folder?

Thanks.

Hey

You should have a folder named mySolver in the related directory. Most likely, you have mySolver.C file, however, the name of the folder is not mySolver.

What you are doing is correct, at least for a local computer.

Verify that you have this variable set and you can access this directory from the login node:

ls $FOAM_USER_APPBIN

If not, then probably you are not loading the OpenFOAM environment properly. You should source the openfoam bashrc file.

I assume that you are compiling from the login node. If you maybe are trying to compile using another node, then make sure that the OpenFOAM environment is also loaded there.

Hello MakisH,

Thanks for the response. But I have problem following how to source bashrc.
I am not the root user of the system and OpenFOAM is installed in a different directory than my home directory. How and what should I change in the bashrc to add these commands?

[MakisH]

What happens if you run the following anywhere? If it displays the help message of blockMesh, then OpenFOAM's bashrc is loaded correctly. If you get an error, then it is not.

blockMesh -help

Wherever OpenFOAM is installed, you should have the permission to read OpenFOAM's bashrc file. Therefore, you need to find it and source it. For example, if you had OpenFOAM 4 installed in the /opt/ directory, then you should run:

source /opt/openfoam4/etc/bashrc

Find where OpenFOAM is installed for you. You need the ./etc/bashrc file from there. What happens if you try to source this file?

You can add this command in your own ~/.bashrc file (which you should have the permission to read and edit), so that it will be executed every time you login. After you edit and save your own ~/.bashrc file, you need to open a new terminal or source it again, so that the environment is reloaded.

Thank you for your help.

I installed OpenFOAM in my home directory and instead used the source command to load bashrc each time I would open terminal.

Hello,
I had the same issue regarding HPC and the $FOAM_USER_APPBIN.
For this reason, I compiled my new solver (mySolver) in one different directory
lets say "/users/myName/OpenFOAM/myApps"
then I created a new alias with the name of the solver which targets its location.
alias mySolver="/users/myName/OpenFOAM/myApps/mySolver"
Then if you go to the case typing nySolver and it runs.. hopefully..

My two cents:
AFAIK, this alias is defined here:

$FOAM_ETC/config/settings.sh

You ought to be able to change the path to some writable place..
