 June 4, 2004, 08:39 sub-surface creation. #1 Chris Guest   Posts: n/a I would like to know whether it is possible to create a sub surface (a 3D-surface out of an existing surface) for calculation purposes (eg calculate the average heat transfer coefficient for a particular zone on a surface).

 June 5, 2004, 00:17 Re: sub-surface creation. #3 Chris Guest   Posts: n/a A surface is not necessarily 2D but can be 3D too. A 2D surface is usually called a plane. I have a 3D surface from which I need to extract data out of part of it. Therefore I was thinking to create a sub-surface from it. Is this posssible?

 June 7, 2004, 12:31 Re: sub-surface creation. #6 Arun Guest   Posts: n/a Hi Chris, Import your data into Tecplot (File --> Import). Then create a sub-zone using Data -->Create zone-->Subzone. Select your I, J and K to create the subzone. Now you can compute your required value using equations in this zone. I don't know if this could be done in Fluent itself. I think Fluent should let you do this. Do experiment the Surface menu. Good luck. Arun
