thank you for clarifying. Does the set of curves used for surface of revolution must lie on XY plane only?
please observe the picture below. A square surface body in a random plane (not XY or YZ or XZ).
I want to reduce the DOFs on each of the node on this body from 6 (for shell) to 4. Like, 2 translations and 2 rotations, along a certain manually defined axis/co-ordinate system (not global). I am doing this to reduce the total DOFs within my model so that the time consumed for analysis contracts. Is this possible?
