Automated Installation
You can install the COMSOL software using an automated installation process with minimal user interaction. This method requires installation from a DVD or DVD image and an answer file.
The answer file is a text file with a specific format that contains predefined settings for the COMSOL installer. If non-ASCII characters are used, the answer file is expected to be UTF-8 encoded by default, but UTF-16 is also supported if the file starts with a byte order mark (BOM).
A template answer file, setupconfig.ini, with detailed usage information is available on the DVD. Create a copy of this file and customize it with a text editor.
When the answer file is ready, start the installation by running
 <drivepath>/setup -s <answerfile>
where <drivepath>  is the media mount point, and where <answerfile> is the complete path to your answer file.
