Graphics Window not responding on computer with Intel Iris Xe graphics chip

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 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 2 - 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
