You can create BCs in a cylindrical coordinate system in LS-PrePost by using the NODE option with *BOUNDARY_SPC_NODE. See the following example and video:

With the NODE option, each node has its own local coordinate system to apply constraints in the radial and tangential direction.

These coordinate systems are created automatically by LSPP:

In the image above, x=radial, y=tangential, and z=axial.

I think cylindrical coordinate systems are in the plan for WB LS-DYNA, but I am not sure when it will happen.
