I ran a static analysis on an assembly and for some reason when i show either the mesh or any of the result plots one of the components is flipped on top of the other components. Has anyone ever seen this happen before? Any thoughts on what caused it? Attached are some screen shots of the assembly. Note this happens whether in exploded view or not. Thanks for any help.
What happens if you animate the results? Does it start out correct and flip or is it inverted from the beginning?
Nope, it's all messed up from the beginning. The only way it looks normal is if no form of results are shown. Mesh, stress, deflection, animation, error, all of it appears flipped.
What type of constraints did you apply? Is there any way they are ambiguous? (like when adding mates if you add a concentric mate and it can flip?) ((Granted I've never seen that in a simulation setup, only mates...))
The mates could potentially be flipped, but the results do not line up with what it would be if it were flipped. Like even if the mates were flipped, the bolt hole should still be concentric in any orientation and it is not. It flipped the part to an apparent completely arbitrary location. The contact restraints are three no penetration component contacts between the three parts. Restraint is fixed on the end face of one tube and load is a remote direct transfer acting on the other tube face of x tension, x moment, and z moment.
Had it a few times before. Seemed to be indicative of a corrupted analysis study, only fix was to start a new study.
Yea, that's what i was figuring something got corrupted. I was hoping it was just a box checked in the wrong place or something so i wouldn't have to run it again. Oh well, i just started it solving again so we'll see.
If the mesh is still showing in the wrong orientation then re-solving may not achieve anything new.
Well i re-meshed it too. The mesh showed correctly this time and the results just finished. They are shown correctly too and the result is considerably different so something was for sure corrupted the first time.
