A Named Single User License may not be used or a network with tools such as Windows Remote Desktop or similar.

ocal computerte computer accessed over a network

In Client-Server mode where you run only the COMSOL Client locally and the COMSOL Server elsewhere on the network, usually on a more powerful computer. The COMSOL Client is essentially the COMSOL Desktop environment whereas the COMSOL Server is the COMSOL computational engine needed for solving.

On a cluster or cloud with no restrictions on the number of compute nodes.In any of the Floating Network License usage scenarios above, the FlexNet license manager software (shipped with COMSOL) needs to be installed and run on a computer somewhere on the network.

INSTALLATION OF A PAID-FOR LICENSE OVER THE INTERNETInstallation of any paid-for license on Windows requires a license file that is sent to you by your COMSOL representative by email. To be able to generate the license file, information about your hardware is needed in the form of a hostid (host ID). The hostid is used to lock the license to your hardware and needs to be sent by you to a COMSOL representative prior to the license file being generated.

Obtaining the HostidFollow these steps to obtain a hostid:1 First open

Obtaining the Host NameIf you have been informed by your COMSOL representative that you need to run the FlexNet license manager for your installation, then you also need the Host Name. The Host Name is encircled in the screen shot above. If your network administrator prefer to use a fixed IP address for this particular computer, this IP Address could be optionally used in place of the Host Name.
