Bye to all,
I recently started using simulated creo 4.0 (m020) to perform some simulations. It is (unfortunately, but so it is and so I have to do) a relatively complex set with a solid geometry and some beams connected through rigid links.
When I start the analysis is a lot tern, 90% of the time fails because some elements are not bound. the error is as follows:the model is insufficiently constrained for the analysis. please review the element connections, properties, and constraints in highlighted entities .
Now if it were some whole component or some beam the error is obvious and it is resolved by giving an eye to the constraints. but what makes me mad is that (when corrected some possible error) it is some elements of the mesh that make up a part. generally happens close to the rigid links, but in the last tests I have happened quite far (always on parts that however possess at least one).
I tried to:
nb: generally (and I was explained so, but it can be bullshit) I was meshare with the autogem and leaving the standard mesh that he should have an adaptive system in the analysis phase. the mesh still seems really gross and I wouldn't trust too much, in fact generally a minimum local refinement where I need it. Is that correct? Is it wrong? What are you doing?
qui an image of what most or less happens to me. By the way they say it's solved, but I don't seem to see big solutions in the thread.
qui instead (clicking on problems with elements) seem to say that maybe it is a mesh size problem? I have however indicated a maximum size for the whole part, but then how do I say that in a certain area I also cool bricks further?

I tried to:
- locally refine mesh (it seems to have noticed improvements, but I do not see the correlation of the thing: How does it do when mesha create elements that for him are released from the neighbors?!?? ! )
- delete and remake the rigid link (even here occasionally improves, but it seems more dictated by the case of having to review the mesh and the data at that point...and still not always it is elements directly connected to the rigid link)
- clear and remake mesh from scratch (also here, it works, but random)
- delete the entire simulation folder (see as above)
- control (with evidence geometry) if the various components see them as connected. That's right. and anyway should have problems with the whole mesh of the element, not to a part.. .
