Failed to compile solution.
There were contacts between the collision object and chassis tubes that were marked as red (by the contact tool). These have not yet been resolved.

MAYBE JUST FIX THIS CAD MODEL AT THIS POINT??? IT’S FAILING AT THE TIP???I checked the CAD and it seems to be setup properly. I’m not too sure why it shows high stresses here.
It might be because the front bottom tube is 1.75in height and causes weird behaviour at the tip of the short vertical tube?
Try to extend the short vertical tube past the front bottom tube (1.75in) in spaceclaim?
This joint has been fully gussetted and the gussets don’t seem to change the stress values.

I wonder if it’s because the contacts aren’t set correctly?
E.g. the small tube and the long tube does not have a contact between them. Force isn’t transferred between them?^This is a bottom view by the way.
I checked the spaceclaim geometry (connected and beam profile is normal) and mechanical contacts (it’s connected with the correct tubes) of this tube.

Gussets were added. Stress did not change at all.
Try to extend beam element to go past the front horizontal tube. Do this in spaceclaim?
Or try super tube now in someway now?Or wait no ---- geometry error causing the tip to fail?
What is strange is that the vertical tube and horizontal tube show low stress. It’s just these tips.

fix collision object interference?

Contacts were only made for the red area tubes. I think that’s why we see high concentrate stresses.
We need to add contacts between the collision object with the other tubes (labelled X ).
Maybe bonded contacts aren’t appropriate, but the other contacts. Since the X tubes are not initially touching, but can be a source of contact during deformation. Apply changes to Top and Top 30, too if it ends up reducing stresses.

Very strange behaviour with a small spike in stress.
We could maybe fix it by adjusting the position of the horizontal or vertical angled tube.
