Changing the License

If you have received a new license file — for example, when adding COMSOL products to an existing license — replace the current license file with the new one. Double-check the contents of this file to make sure it lists the products that the license includes.

When the license file has been changed, you must restart the license manager; otherwise, it continues to use the old license file still in memory.

restarting the license manager

To restart the license manager, make the license/$arch directory under the COMSOL installation directory the current directory, then enter the following commands:

./lmdown -c ../license.dat

./lmgrd -c ../license.dat -l /var/tmp/comsol52a.log

When installed as a service on Linux distributions with systemd according to the instructions, you stop it with the service lmcomsol stop command and start it with the service lmcomsol start command.

obtaining a hostid

If COMSOL is already installed on your license server, you can determine the hostid by executing the lmhostid command
