Static simulation problem

Hi all

I have a problem. I managed to calculate my chassis once and since then I can't do it. It runs and crashes SolidWorks after a while.

Is it a design or PC issue?

I'm attaching the file if you want to test.

Thank you in advance.

Hello

Please specify the version of your file / solidworks.

Good evening be_295,
Yes, your design is a bit complex and doing RDM with edges touching each other will create crashes on SW. If it's to do a pre-simulation to test, you can, at the bottom of your file, add all the bodies together.
