Configuring the Host System

Once the NSU3D solver and associated tools are compiled, the user should add the executables to their system PATH. This can be done either on a system or per user basis. As an example, the login script for the bash shell, .bashrc (in the root of each user's home directory) can be used to add the path for a specific user by adding the following lines:
​
PATH={nsu3d-install-path}/solver/EXECS:$PATH
​PATH={nsu3d-install-path}/tools/EXECS:$PATH
export PATH

The following command can be used to see if the path is set correctly:

which PRENSU3D.sh

It should return the location of the pre-processing script. If not, then it may be necessary to re-load the bash configuration:

source ~/.bashrc

If you are not using the bash shell or would like to set the system-wide path, then there are numerous on-line tutorials on the subject for Unix/Linux sytems.
