Hi All,

I am trying to calculate mass flow rate at 12 HVAC vents opening. These openings are not defined as patch or face. They are interior of the domain. I want to define plane/rectangle of a give size at these opening locations to calculate the mass flow rate through them. But when I create a plane in paraview using sources > plane, the plane doesn't have nay data field - U or p.
Please help me to calculate mass flow rate at arbitrary plane in the domain. When I use slice or cut plane, it cuts through the whole domain, which I don't want.

Regards,

Manoj
