I have a 2D fluid flow model with a flow through a channel with rectangular cross-section. There is one inlet with non-zero inlet pressure and outlet with zero pressure.
After solving, in order to compute the volume flow rate , I started by going to Definitions > Model Couplings > Integration. I created a integration for the outlet boundary (which corresponds to the height of the channel in 2D view) and named it intop1
Then I went to Study > Update Solution (I had already computed the solution), then I went to Results > 1D Plot Group, then 1D Plot Group > Global.
In the Global plot I added the expression, intop1(fsi.U)*W which gives me values in m^3/s....where W is a constant and is the width of the channel.
Can someone confirm that this is the correct way to calculate volume flow rate?
Thank you.
