Submodel: Coincident nodes

[SamiKarim]

Hi!

I'm trying to do a simple submodel analysis of a flange connection. I have run the global model but when trying to run the submodel I run into some problems.

The problem is that in the contact area between the two flanges I have two nodes, one node on each of the flanges that share the same position so when trying to run the submodel the node on the lower flange gets the displacement that the upper node have.

I have tried to specify the driving region by creating a element set for respective flange and the entering the name of the sets when applying the submodel boundary condition. But when running the analysis I get the error that ABAQUS can't find the specified set in the .prt file.

How should I do?

Are you using part- and assembly definitions? Is that supported in submodelling? I'm not sure. Check the manual regarding this.

I tried both assembly and part definition. None of them worked. The manual tells that when using part definition the whole set name should be put in e.g. "assembly-1.part.etc..." and when using assembly definition it should be enough with just the name of the set.

Solved the problem, I had specified a too small exterior tolerance, changed the value from 0.01 to 0.05 and it worked fine. I used assembly set definition and put in the set name under driving region.
