Installing your STAR-CCM+ license for the first time

When you are installing STAR-CCM+ for the first time you will receive a license file with the name “License_cdlmd.txt”. Note, the license will be named “license.dat” if you download it from the Siemens license administration tab.

The server line of your STAR-CCM+ license will look like this:

SERVER host_name 0a1b2c3d4e5f 1999

The SERVER line contains the details of the license server machine to which the license has been tied, as described below.

• "host_name" will be the host name of the license server machine and can be edited if incorrect.  
• "0a1b2c3d4e5f" will be the MAC address of the active Network Interface Card on the license server machine.  If the MAC address is incorrect, a new license must be generated by Siemens.
• "1999" is the default license server port.  This is the initial port over which other machines will contact the license server machine to request a license.

You may find the Host name and MAC address by following the step-by-step directions in this article: Determining the Hostid for Licensing. Note, the terminology in the provided link uses the term "Hostid" in reference to MAC address.
