Default Symmetric condition

Quick question,

I splitted a cylinder into a 90 degree model and I run a 3D simulation. So the splitted faces has symmetric bc. So, when fluent gives me the volume flow rate it is for the whole model or just for the 90 degree mod?

Surely you can do some hand calcs to check this?

I haven't looked at you problem obviously, but I think you should be using periodic boundary conditions, not symmetry. Symmetry would work for a 180 degree model.

The flow rate is just for the sector alone and not the full thing. Unless you can guarantee no swirl down the pipe, use periodic zones instead of symmetry.
