Creating lines for surface integrals

October 16, 2002, 14:02

Hi to all,

I am modeling the flow in two coaxial pipes (2D axisymmetric domain), and I would like to calculate some surface integrals over the annulus only. The problem is that, if I define a line (using Surface Line/Rake), Fluent will create a line also over the inner pipe (It always creates lines from the axis to the farthest wall), even if defined the correct values of end-points' radial coordinate.

Does anybody know how to solve this issue?

Thank you very much.

You have to use a rake where you can specify the begin- and end-points.
