Hello,

When working with shell elements does it matter which face of the mid-plane you select to contact another shell? I am analyzing a brazement and the best way to represent the model is to utilize shell elements due to the thin features. This issue that I am running into is where a contact set that mates two shell faces together and randomly neglects to account for itself while the analysis runs.  I had one lucky time where the constraint accentually functioned as it should but then regressed in the next run.  I understand that you can look at the shell “top and bottom” in the colors generated in the mesh; however, nothing seems to be working.  I have deleted and re-contacted multiple times.     I am in 2011 by the way

Please help!

Chris
