I have 2 surfaces mated using glued contact. I have run a modal analysis. When I view th results deformation, it looks as though the 2 surfaces are separating even though they are glued. Is this just an artifact of the deformation plot?
EDIT: I can almost answer my own question. When I look at other connection regions, I do not see this separation. What could be causing it in this particular location?
Solved! Go to Solution.
It certainly appears that they are separating, if you would send us the model, we can take a look at it.

Hi Mark - I am currently re-running after regenerating the contact regions manually and adjusting the default Nastran ERROR value. I will let you know what happens. Thank you for your help.
The default value of ERROR was .5" and the original connection regions were defined a lottle awkwardly, which may have been the result of some small features in the vicinity of the regions. Decreasing ERROR and defining the regions explicitly seems to have worked.
I will look into the glue factor too. All parts are same material (aluminum) and mesh density.
