Hi Srikrishna,

have you found a solution to your question? I ran into the same problem I think. After having a surface geometry and a Quad4 mesh I get two errors whn tyring to open the ACP setup.

I get an error in ACP saying: 'StandardShellView' object has no attribute 'shell' and another error in Workbench saying: 'At least one exception occurred during the refresh that made it impossible for ACP to complete the process'. 

Do you have the same problem? Or did you find a solution for yours?
