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.

Solution

We expect that a future driver update will resolve this issue. In the meantime, we suggest one of the two workarounds below:

Workaround 1 - For all 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 2 - Only for COMSOL Multiphysics 5.6

  1. Download the patch from the Related files list below.
  2. Extract the ZIP archive.
  3. After ensuring that COMSOL Multiphysics is not running. Copy the two files you have extracted from the archive to the folder bin\win64 in your COMSOL installation.

After installing the patch, 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
