How to model a full 3-D cylinder in cfx44?
 
Users, How to build the geo model for full 3-D cylinder? In build I only build the 2-d model and 3-d model but only sector not full cylinder with cylinder coordinate system. if someone know, please tell me without hesitation!

thank a lot. S.Ding

Hi,
As far as I know you can't do it the way you're intending. If you want to solve a 3-D grid in cylindrical coordinates you MUST have an axis at y = 0 (In CFX-4 -> Cartesian = [x,y,z] and Cylindrical = [axial, radial, tangential]), i.e. r=0. Thus, you'll have two more symmetry planes in both boundaries of tangential direction. But if you still want to solve the full cylinder, I believe, you must use a cartesian coordinate system.
