Filtering a volume to calculate in a subvolume

Please login with a confirmed email address before reporting spam

Dear All, I have two crossing pipes where I solved the flow (two inlets and two outlets). In the POSTPROCESSING, I would like to ´select´ one cylinder and have the possibility of calculating the integral of the vorticity.

I employed the Filter option (3D Plot Group->Volume->Filter) to view the vorticity distribution, just imposing to see the domain that satisfies "x^2+y^2<r^2´,

being r the radius of the cylinder. But I do not find the way to get filtered the data to calculate the integral of the vorticity.

Any suggestion is welcome. The version is 4.4. Thanks!
