There is no third point. There are 2 points which are connected with the line. I defined it as a beam. I put one contact between 2 points and the inner face of the shell. There was no an error in my analysis.

As you see in this picture, I changed the location of the points. Although they do not have a connection with the inner face, Ansys is solving this analysis again.

According to the rules of static analysis in Ansys, all parts must have a connection. In this picture, there is no connection between the points and the inner face of the shell but it is solving the problem.
How can I declare this bug to Ansys authorities?

When I am designing a cylinder with a shell part, I do not have a problem. However, I encountered a problem when I designed a cylinder with a shell part.
