Integration over portion of a surface
I would like to know if there is an easy way to calculate a function on a portion of a surface in CFX Post. For example, what would be the easiest way to integrate the wall shear stress in the fully developed region of a duct flow? So far, the only work around I can see is to run the simulation, observe the flow development length, modify the geometry to split the duct into two regions, and then rerun the simulation.

Use a contour line to define your fully developed region on the surface, make a user surface defined by the contour, do the integration on the user surface.

Thank you for the reply!
I let my axial dimension be the contour plot variable, made several user surfaces for each level of the contour in the fully developed region, and then combined them in a surface group. I'm assuming that's the easiest method. |
If it works then it is all good.

Is there way to apply this method to volumes?
|
Apply what method?
If you mean calculate functions on sub-volumes, then yes. Define a volume as a sub-region of the full domain and calculate the CEL expression on the defined volume. |
