Hello guys, I am a product designer from the UK, and I am currently working on a motorcycle project. I am learning to Use solid works simulation and I was wondering if someone could help, please.
I am testing a basic frame, and those are the error I get.

So first I the issue was interference between the beam, therefore I saved the file as assembly, and cut each rode by .1 mm so they would not interfere, and after saved it as a part. I trimmed each rod at with a swipe therefore not space between them, but still it would create interference, that s explains the .1 offset cut.

What I am doing wrong, the test, the connection between the rod, I really don t know
Thank you for your help in advance!!!
