CFX error in solving 2D problem

bestniaz · April 30, 2015, 02:18

Dear Friends
Can anyone help me in solvingCFX problem. I meshed the simple flow over cylinder (2D) and then tried to give boundary condition in "setup". But when i clicked on "setup",,it give error

Application Error in CFX-Pre: ERROR
There was a problem importing the mesh from the requested file.
The importing process reported the following problem:

Model "Model" does not have a valid mesh associated with it.

Body B61 is an unsuppressed surface body that does not enclose
a volume. Only 3D volume meshes can be imported. If your model
contains valid bodies as well as surface bodies then suppress
the surface bodies and remesh before continuing.

ERROR: Failed to export model.

Does this mean that CFX cant solve 2D problem? Please help me I am new in this area.

No 2D.
Extrude the elements to small width. Put sym or cyclic BCs on side walls to mimic the 2D problem.
