Error Message on Not Connected Nodal Loads and Supports After Splitting Pipe Cross-Section

I have generated a surface from a restrained pipe cross-section. Now, an error message appears after the calculation, saying that the nodal loads and nodal supports are not connected. What can I do?

Answer:

After generating a surface from a pipe member, this is no longer connected to the original nodal support. A line support is recommended for the newly created lines at the pipe start; see Image 01.

Also, the nodal load is no longer connected to the original member. In this case, a crossing of rigid members is recommended for the load introduction; see Image 02. Thus, the load is transferred to the boundary lines of the surface.
