Flow_rate trough a "Coanda" grating in Paraview
 

Hi everyone

I'm new in CFD, I am trying to simulate the performance of a "Coanda" grating , I`m using SimFlow for the simulation and Paraview 4.3 for the post processing. In fact what I need is to determine the flow rate trough the grating, I have been searching how, but I couldn't find anything.

I found this response in another post but when I did that I could not determine the flow rate:

"step 1:In filters--->alphabets you select calculator option.

and then a block will be opened in that you select scalars---->U_X or U_Y depending on the direction you want. and name it in the Result array name as flow rate and then click apply.

step 2: and the n select filters---->alphabets----> integrate variables option.

step 3:It will display one window in that you select the variable name you have given flowrate

step 4:Now, filters----->alphabets---->plot selection over time

now click the copy active selction option and then press apply"

Could you help me please
