I want simulate 2D geometry in CFX-11 SOFTWARE.is it possible
possible means:how to load it.
Thanks

Yes, there is a way t osolve 2D in CFX..

please go thru the link below

yes, it is possible to simulate a 2D geometry; you need to make a trick
Suppose that your 2D geometry is in the XY plane, then you extrude the geometry in the Z direction putting only one element (two nodes). Now you have a 3D geometry with one element in the Z direction. Finally to simulate a 2D problem you need to specify symmetry condition in the two XY planes. Thats all

Huguichu.
Hi,in CFX-11 WHERE IT IS OPTIONS,
i have 3D geometry in ICEM file,i exported in CFX-11,IN THAT HOW TO EXTRUDE IN Z DIRECTION,
where it is options,which option should considered.
Thankyou

In ICEM or other mesh generator:

Suppose that your 2D geometry is in the XY plane, then you extrude the geometry in the Z direction putting only one element (two nodes). Now you have a 3D geometry with one element in the Z direction

IN CFX:

Export your 3D mesh with one element in Z direction and to simulate a 2D problem you need to specify symmetry condition in the two XY planes.
