Installing on Linux

Installation Over the Internet

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.

A trial license can be given to you with the intention to test the software without any payment obligation for noncommercial or nonproduction use. This option is not available in all regions. For installation of a Single User Trial License on Linux, you can follow the same instructions as for a paid-for license.

Obtaining the Hostid

Follow these steps to obtain a hostid:

1	Start a Terminal window.

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 Host Name

If you have been informed by a COMSOL representative that you need to run the FlexNet license manager for your installation, then you also need the Host Name:

1	To get the Host Name, start a Terminal window.

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 Host Name. 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 Host Name, 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:

1	Click the link for downloading the software as given in the software download email from your COMSOL representative. This link is identical or similar to: www.comsol.com/product-download

2	If you haven’t already created a COMSOL Access account, you are prompted to create it. While creating the account, point to your license file (license.dat) to associate it with your account information.

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.

3	Continue with the instructions in the next section Downloading the COMSOL Installer.
