2D Flow Rates

Please login with a confirmed email address before reporting spam

Hi, I am doing some rather basic CFD work looking at how different objects obstruct the flow of fluid in a channel. My model is essentailly a square with different sized circles placed into it. The left side is the inlet (constant pressure) and the right side is the outlet.

I have created surface plots of pressure and velocity, however I would really like to see the 2D flow rate on this. The only way I can think of doing this is to create an expression multiplying the velocity by the height of the element, giving me units of m^2/s. Unfortunately, I can't seem to do this. Does anyone know how to get such a result?

Thanks
