Obtaining the Software

Download the COMSOL software to a temporary location. This installation file  COMSOL55_dvd.iso is an ISO image.

Installing the Software

To install the tool:

  1. Extract the COMSOL ISO file into a temporary directory:

    You can use any extraction tool, such as WinZip or WinRAR, or just click the iso file (Windows 10) and it will be auto extracted.

    If you do not have an extraction tool, you can download the freeware 7zip utility located at

  1. Navigate to the location of the unzipped COMSOL ISO package, click setup, and then choose New COMSOL 5.5 Installation.
  2. At the license stage of the installation, use the following data:
    • Port number: 6601
    • Hostname:

Note: Always check CADpass Licensing Information for the latest Port number and Hostname (Server Name).

  1. To validate your installation, click Check.

    Note: The software may ask you to choose the type of license to use. You may choose a COMSOL Multiphysics license, or if you are comfortable installing a COMSOL Server, you may choose a COMSOL Server license. The latter requires extra configuration steps. With a server license, a COMSOL Multiphysics application (designer created) can be run in major web browsers on platforms. If you need more information, search the COMSOL website before determining the type of licence you need.

    The License Information window displays the valid licenses that you have.

  1. Click Close.
  2. You can browse the third-party tools folder, which is installed on your local machine, for LiveLink products (Figure 2).

These products will be linked with the COMSOL tool.

  1. Continue with the installation and accept the remaining default options, as shown in Figure 3.

Figure 3: Finishing the COMSOL Installation

  1. After the installation is finished, click the COMSOL icon on the desktop.
  2. After it is running, in the COMSOL GUI, navigate to File | Application Libraries | Module (for example, the AC/DC Module).
  3. Choose an example to open, and run the simulation to make sure everything is working correctly.

See Figure 4 for an example.
