Hi @dengerer!
Are you familiar with the Result Controls on SimScale? You can post-process a vast amount of quantities with this tool. I posted a project by @ahmedhussain18 yesterday covering the Reaction Forces: Thermal Shock Analysis
If you scroll down you can see the post-processing images. By copying the project you can see how Ahmed did that. It is pretty easy! Of course you can post-process other quantities like acceleration, displacement etc.
Is that what you were looking for?
Best,
Jousef
