Problem Description

COMSOL is slow to open and the operation in the User Interface feels lagging on my new computer. What can I do?


The most common reason for this kind of behavior in newer computers relates to the power settings. Newer computers often come with a power plan implemented by the computer vendor that is optimized for energy efficiency. Such a power plan can limit the speed of COMSOL. To investigate this, do the following:

  • Open the Control Panel.

  • Select Power Options.

  • Select the High performance power plan (or even Ultimate performance if available).

Power plan options in the Control Panel

  • Start COMSOL again. You should see a marked improvement in speed.
