-You will also need to set up your job environment to use your license. If you are using CD-adapco's online <i>pay-on-usage</i> server, the configuration is rather simple. If you are using an internal license server, please contact [[technical support]] so that we can help you set up the access to it.
+When submitting jobs on a cluster for the first time, you must set up the environment to use your license. If you are using CD-adapco's online <i>pay-on-usage</i> server, simply create a  <code>~/.licenses/starccm.lic</code> file as shown in the <b>POD license file</b> section above and license checkouts should immediately work.  If however you are using an internal license server, then after creating <code>~/.licenses/starccm.lic</code> you must submit a problem ticket to [[technical support]] so we can help co-ordinate the necessary one time network firewall changes required to access it.   If you still have problems getting the licensing to work then try removing or renaming file <code>~/.flexlmrc</code> since previous search paths and/or license server settings maybe stored in it which conflict with your current <code>starccm.lic</code> settings.  Not e that files from previous may have accumulated a significant amount of disc space in hidden directories named <code>.star-version_number</code> if you have run many long jobs in the past using older slurm scripts or if you regularly run starccm+ in gui mode.  These can be removed periodically by carefully running the command <code>rm -rfIv ~/.starccm*</code> where the v option will list everything that is erased.

-Note that at [[Niagara]], the compute nodes mount the <code>$HOME</code> filesystem as <i>read-only</i>. Therefore it is important to define the environment variable <code>$STARCCM_TMP</code> and point it to a location on <code>$SCRATCH</code>, which is unique to the version of StarCCM+. Otherwise, StarCCM+ will try to create such a directory in <code>$HOME</code> and crash in the process.
