Stress analysis weirdness

In the same model, only working conditions 6 and 7 are added on the right side. How come the EXP working condition cannot be passed? Logically speaking, EXP working conditions are all derived from OPE-SUS, so they should remain unchanged.

Try placing the order of L6 between L3 and L4. Your software version is too low. New versions calculate thermal primary stress by default.

Mine is version 5.3. Still not working. What is the default working condition for calculating thermal primary stress in the new version?
Reply #42021-07-28
That means the primary stress in the thermal state is exceeded. In addition to the normal working conditions, the new version also has an additional ALT-SUS, which is used to measure the thermal primary stress.

Your ALT-SUS is actually my right L3-L6
Reply #62021-07-28
Do you know why L3-L5 exceeds the limit? Because there is no change after I operate OPE-SUS before and after

It shows that the bracket is detached at the operating temperature. Isn’t that why you calculate the thermal primary stress?

It seems that the secondary stress has changed
