Installing on Linux
Installation Over the Internet
installation of a trial license over the Internet
A trial license can be given to you with the intention to test the software without any payment obligation for noncommercial and nonproduction use. This option is not available in all regions.
Installation of a Single User Trial License requires a license passcode. A passcode has a form similar to FFFFFFFF-TYUS-123456-1234567-123456789.
This is usually sent to you by your COMSOL representative by email. Once you locate your passcode, follow these steps to prepare for download and installation:
1
2
If you already created a COMSOL Access account, you can associate the license file with your account on the COMSOL Access page under Manage Licenses at www.comsol.com/access/licenses.

A license passcode can also be used for class kit licenses (CKL).
Continue with the instructions in the section Downloading and Installing the COMSOL Software.
installation of a paid-for or Trial license over the Internet
Installation of any paid-for license on Linux requires a license file, which 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 Hostid
Follow these steps to obtain a hostid:
1
2
Enter cat /sys/class/net/*/address
This displays all physical Ethernet addresses (also called MAC addresses) which consists of six bytes displayed as six pairs of hexadecimal digits such as 00:40:05:16:E5:25. Choose one that does not consist of zeros only.
Obtaining the Hostname
If you have been informed by a COMSOL representative that you need to run a license manager for your installation, then you also need the hostname:
1
2
Enter hostname at the terminal prompt.
If your network administrator prefers to use a fixed IP address for this particular computer, this IP Address can be optionally used in place of the hostname. For more information on license manager installation see License Manager Installation on Linux.
Obtaining the License File from a COMSOL Representative
Send the hostid information, as well as hostname, if applicable, in an email to your COMSOL representative, who responds by email including an attached license file (license.dat). Save this file to any location on your computer. You need to refer to it during installation. A trial license file for Linux cannot normally be edited or changed in any way by the user but has to be identical to the one sent to you by a COMSOL representative. However, if you were sent a license file that requires a license manager, then minor edits are required. For information on the type of license file required for installations using a license manager, see The License File.
Registering with COMSOL Access
Once you have saved your license file, follow these steps to register or login to COMSOL Access and to start the installation:

If you already created a COMSOL Access account, then you can associate the license file on the COMSOL Access page with your account under Manage Licenses at www.comsol.com/access/licenses.
