COMSOL Multiphysics is a finite element analysis, solver and Simulation software / FEA Software package for various physics and engineering applications, especially coupled phenomena, or multiphysics. COMSOL Multiphysics also offers an extensive interface to MATLAB and its toolboxes for a large variety of programming, preprocessing and postprocessing possibilities. The packages are cross-platform (Windows, Mac, Linux). In addition to conventional physics-based user interfaces, COMSOL Multiphysics also allows for entering coupled systems of partial differential equations (PDEs). The PDEs can be entered directly or using the so-called weak form (see finite element method for a description of weak formulation). An early version (before 2005) of COMSOL Multiphysics was called FEMLAB.


Installation of COMSOL Multiphysics on a Mac OS X PC

  1. Download the COMSOL package: Comsol 5.5

  2. Connect to engineering VPN

  3. Mount the Comsol55.iso package and navigate to the mounted location.

  4. Open the ‘setup’ file to start the installation. If the install does not start check to see if your macOS version is compatible OR if you need to provide admin access (steps on how to allow access for Comsol are located at end of page)

  5. The COMSOL 5.5 installer will open, select your language, and click Next.

  6. Select ‘New COMSOL 5.5 Installation’.

  7. Accept the license agreement.
    Change License Format to <port number>@<host name>
    Enter for the Port number: 1718
    Enter for the Hostname:
    then click Next.

  8. Check to make sure all settings are correct and continue to click Next.

  9. Once you are ready, click Install, which will proceed through the installation.

  10. To run COMSOL, make sure you are connected to engineering VPN and then run the program like you normally would.

NOTE: You can download the previous versions if needed.

NOTE: You may need to allow administrative access to the program.
  1. CMD + space Type “Security and Privacy” -> General [tab]
  2. Click the lock to allow admin/sudo access. Select “Allow apps downloaded from App Store and identified developers.” Allow the software to run as shown in the screenshot

Patch for Users Using Mac OS X Yosemite

If you are having issues installing or running COMSOL Multiphysics, and you are running Mac OS X Yosemite (10.10.x), a patch has been released to resolve this issue:
