Is 2-d axi possible?
 
Good Day, everyone! I wish to ask guru: Is 2-d axi possible? And how to set up it&

Hi!

CFX is only a 3D solver. If you want to compute a 2D or an axisymmetric problem, you have to solve this as a 3D problem with periodic or symmetric boundary conditions.

Hi Vlad,

2D is not available, but you can generate a mesh with one element in the circumferential direction and either symmetry or periodic boundary conditions on the side.

CFX-Mesh 9.0 will allow you to create a mesh like this from a revolved geometry. You can also generate a mesh like this in ICEM CFD by first creating your 2D mesh, then revolving the mesh about your axis.

Regards, Robin

Hi Robin Does ICEM automatically manage to collapse the edge og the cells lying on the revolving axis? Or do I need to do something specific.

There is an option to merge the nodes at the bottom of the panel that does the revolve operation.
