Shell slide on rigid body
I am quite new in ANSYS and have a problem with my model.
I have a part which is made of lot of shells. This part should slide on the rigid body, see figure 1.
The part should be able to move in the positive z-direction, but not step throug the rigid body (negativ z-direction).
In Figure2 you see the connection between the shells and the rigid body.
You see the details of the rigid body in figure3.
When I start my calculation i get the error "Not enough constraints..".
I want to get an fixed support on the rigid body. Can anyone tell my how to do this?
I also tried to use an "Compression Only Support" instead of the rigid body, but I can not choose my shells there fore.
