Problem Description

COMSOL Multiphysics crashes silently when modeling. When you try to restart COMSOL it may crash immediately.

Solution

The cause of this behavior can be a hardware error on some part of your memory cards. It is recommended that you run a memory check to make sure that the RAM memory is working well. Windows 7 and later have a built-in memory diagnostics tool that you can run. How to run it is described here:

Replace any faulty memory cards in your computer that the diagnostics tool might find.

If you are using an older version of Windows you can instead download Windows Memory Diagnostics from here:
