min z,max z : -0.001,0
all dimension in meters. As seen the last dimension is the extruded one which it 1 mm so is it sufficient or i need to increase extrude factor (currently 1) at advance import options?
use ICEM CFD software to see all the characteristes of your mesh or get running and see the features via post cfd through the solution.

Hi, Ghorrocks,
I've created a 2D mesh in ANSYS Mesh. Then I've tried to import it in CFX (wishing it would extude it 1 cell thick), but a message informs me that there has been an importing error, since "Only 3D volume meshes can be imported".

I need to run a "2D" simulation in CFX. What can I do?

Many thanks

You should make your mesh 1 element thick. Set Solver Preference to CFX in ANSYS Meshing and it will do the job.

Hello, Antanas!
I had already set, in "Solver Preference" CFX.
But, as I reported before, when I try to import the surface mesh to CFX, then I get the previous merror message.
I really really neeed an help, thanks!

I thought that you export your mesh to a file and then try to import it in CFX. So in you case you can:
1. Export mesh to say fluent file format. Then open CFX and import it (don't connect Mesh and CFX analysis systems).
2. Extrude your geometry in DM and then generate mesh.

I exported the mesh in fluent format, and then imported it in CFX, and now I can see it has already been extruded!!!! THANKS SOOOOOOOOOOOOOO MUCH!!!!

Now I have a new question:
The thickness mesh (the contour of the 3D mesh, which is 1 cell wide) cannot be separated in portions. And I need to create different bundaries like inlet, outlet and so on... How can I "brake" the "wall surface body" (that's the name of the contour) in order to create the different bundaries?

Thanks again!
