OpenFOAM under other users

Hello,
I'm running an HD install of CAE Linux and am interested in running OpenFOAM 1.2 from accounts other than root. In attempting to do this, I've up to now:

1) Copied the .bashrc-CAE file from the root directory over to the users home directory
2) Created an OpenFOAM alias in the users home directory
3) Modified the permissions to allow the user to execute the necessary file.

Having done this, launching the CAE Command Line Tools produces no errors, and everything appears as it does for root. However, when I try to launch FoamX, I get the error below.

/home//OpenFOAM/OpenFOAM-1.2/bin/runFoamXHB: line 122: nsd: command not found

Let me know if there are any suggestions, and for now, I'll keep using the root account, which is working fine.
Thanks,
Dustin
