Avoiding Power Throttling on Windows

问题描述

When COMSOL Desktop runs in the background or behind the screen lock on Windows 10 or 11 you might notice a slowdown due to power throttling.

解决方法

Test solving a large model while working on something else in another Window. Make a note of the solution time from the Log window.

Start a command prompt as administrator and type the command

powercfg /powerthrottling disable /path "C:\Program Files\COMSOL\COMSOL63\Multiphysics\bin\win64\comsol.exe"

Test solving the same large model while working on something else again. Check the solution time in the Log window again. It could improve as much as 10-20%.

To list applications with power throttling disabled

powercfg /powerthrottling list

To restore power throttling:

powercfg /powerthrottling reset /path "C:\Program Files\COMSOL\COMSOL63\Multiphysics\bin\win64\comsol.exe"

Note: make sure you have enough cooling on your system when disabling power throttling.
