Problem Description

I recently bought a laptop with the new Intel Iris Xe graphics chip. When I run COMSOL Multiphysics on it the Graphics window does not appear to respond to mouse movements.


There are three suggested workarounds for this issue.

Workaround 1

Update your Intel Graphics driver to at least version The fix for this issue is included in that version of the Graphics Drivers.

Workaround 2 - For older versions of COMSOL Multiphysics

Run the cross-platform GUI for COMSOL Multiphysics instead of the default .NET GUI. To start COMSOL Multiphysics with the cross-platform GUI, launch the file comsolxpl.exe from the bin\win64\ directory in your COMSOL Multiphysics installation directory.

Workaround 3 - Only for COMSOL Multiphysics 5.6

  1. There is a fix for this issue included in Update 1 for COMSOL Multiphysics 5.6.
  2. If you have not yet updated your installation, you can initiate the update by going to File > Help, and select Check for product updates in COMSOL Multiphysics.

After installing the update, you need to launch COMSOL Multiphysics with the option -disablehwacceleration. You can accomplish this by editing the COMSOL Multiphysics 5.6 icon on your desktop in the following way:

  • Right-click the icon and select properties.
  • On the Shortcut tab, add a space and then paste -disablehwacceleration to the Target field.
  • If you have installed COMSOL Multiphysics in the default installation directory, the full text field should look like: "C:\Program Files\COMSOL\COMSOL56\Multiphysics\bin\win64\comsol.exe" -disablehwacceleration
