Modeling 2D Geometries
 
Hi,

I want to model a 2D geometry in ansys (12.1) and I am not sure if I my method is the right one. First I drawed polygon lines with a closed end, and then I extruded this sketch. My problem is that the geometry becomes 3-dimensional with the extrusion. And it is impossible to put the depth (for the extrusion) to 0mm or even 1e-1000mm (i.e. as thinn as possible) . So my question is: is there another way to create simlpe faces in ansys or does it only go by extrusion?
Thanks in advance for an answer!

P.S.: Sorry if this is a stupid question but I am new with ansys and I am desperate ;)

Surfaces from Sketches
 
3 Attachment(s)
Extrude is for 3D data… If you just want to create a surface from a sketch, then go to “Concept => Surfaces from Sketches”.
Attachment 2863
This will prompt you to select your sketch(es). Then click generate.
Attachment 2864
The SurfaceSketch will appear in the model tree with its associated Sketches…
Attachment 2865
Next you will need to select the edges to apply named selections for things like inlets and outlets…
