How to apply a displacement/boundary in cylindrical coord

How to apply a displacement/boundary in cylindrical coord

How to apply a displacement/boundary in cylindrical coord

(OP)
Hi all,

I am modelling a curved beam with tangential boundary conditions.

I use the command "CSYS, 5" to activate the global cylindrical coordinate to model my finite elements, and it is ok. However, when I apply the BCs by "D, ...", all of these restraints are in cartesian coord although I do not change the active coordinate. The problem is the same when I apply a displacement.

Another thing is strange to me that the Ansys GUI seems don't understand the model when the DSYS is set to 5 (cylindrical).

Any inputs are highly appreciated. Thank you.

You'll need to rotate the nodes using the NROTAT command.

Thank you very much for your answer. Now, with the use of NROTAT, I can apply the desired BCs.
