Hi, I've tried to install openFOAM using my user, but I've see that it changes the default gcc compiler to the one shipped with openFOAM. So I'm wondering if it is better to create a user specifically for OF15 so that to mantain the base system as shipped by the distro. Then to use OF and paraview I've just to log as the newuser using ssh -X, is it correct? Xwang

No, in my opinion it is better to eat vegetables. |

You can use the same user for OF and other requirements.
It is all about sourcing the correct variables. If you remove/or better hide the following line from your .bachrc file, you can use default gcc compiler of your Linux (not OF) . $HOME/OpenFOAM/OpenFOAM-<VERSION>/etc/bashrc AND You can also create a seperate user for OF (and ParaView) and then just log into that system, by rebooting or logging off current user. |

Or you can just use your system compiler by making a switch in your $WM_PROJECT_DIR/etc/settings.sh:

The fact that system compiler is 4.3.2 instead of openfoam 4.3.1, can create problems? Xwang

You have set the WM_COMPILER_DIR to /usr. You can try that it works by simply setting this variable in your shell and then run foamInstallationTest.
To have the correct setting in all shells, I have added the red lines in $WM_PROJECT_DIR/etc/$settings.sh: .... WM_COMPILER_BIN=$WM_COMPILER_DIR/bin WM_COMPILER_LIB=$WM_COMPILER_DIR/lib$WM_COMPILER_LIB_ARCH:$WM_COMPILER_DIR/lib ;; System) export WM_COMPILER_DIR=/usr ;; esac ... |
