You will need to have your own license in order to use this software. A remote POD license can be purchased directly from [https://www.plm.automation.siemens.com/global/en/buy/ Siemens]. Alternatively, a local license hosted at your institution can be used, providing it can be accessed through the firewall from the cluster where jobs are to be run. | ||

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 [mailto:support@computecanada.ca contact us] so that we can help you set up the access to it. | ||

Otherwise, StarCCM+ will try to create such a directory in <tt>$HOME</tt> and crash in the process. | ||
