Hello,

I am Using Ansys 14.0. I want to define a surface (a circle) on my 3-d geometry. But the design modeler software needs thickness and does not creates a surface in a 3D geometry. I need to determine this circle on a part of my geometry, because I need to calculate something specifically for this circle are in FLUENT. So I need to define a name for it in (named selection) then I will be able to select that in FLUENT and calculate for that area. What should I do?

Please help me with this. Thank you.

Hi,

The thing is to have nodes on this geometry in order to define it within Fluent. so it has to be part of your geometry definition: I think you need to split your geometry where you want to put the disc. Then split that face with a disc. And define the disc as "interior".

However, if it's only post processing, you may be able to do this in CFD post directly.

Marion.
