Hello Fraternity,

I am performing a contact analysis between a solid cylindrical shell contacting a concentric solid cylindrical ring of larger diameter. If I perform contact analysis by defining contact surface pairs, I can see the CSTATUS showing the colors representing sticking and sliding. When I perform the same analysis using General Contact, the CSTATUS shows no contact (whole model is blue).

What could be the reasons ? Any suggestions, comments please.

contact details:

Tangential Behavior - penalty method ; Normal - 'Hard' contact with Direct constraint.

Ring inner surface is Master and Shell outer surface is Slave.

Mesh with C3D20R solid elements.
