I am trying to define boundary condition in a cylindrical coordinate system in Abaqus. I have to implement an SS4 boundary condition defined as:
1. displacements: u (axial) = v (circumferential) = w (radial) = 0
2. moments: Mx (bending moment about circumferential axis) = 0
Point (1) seems simple enough, but I am confused about point (2). I'm not sure how this is reflected in restrictions on rotations about the axes.
