Hi I have a question with result on my 2D channel flow. After I run calculation the result shown the flow rate is equal at any point since the inlet to the outlet. I want to compare my calculation with my ansys fluent if it the same or not. I already calculated the inlet flow rate and the result is the same as ansys and I have try to find the manual on fluent but I don't see an equation that can calculate the flow rate in the outlet and cross-section line. My question is how could I know any equation that can calculate the outlet flow rate and cross-section on the channel?

There's an area option in the panel you've shown. I'd use mass weighted average to get the velocity (read the definitions before asking why) or Flux (another report) to check what goes in comes out. If the latter condition isn't reached the solution isn't converged!

Thank you for advice.
what I mean is that I would like to compare the result of average velocity of the cross-section area at any distance along x-axis by getting from ansys result (Mass Weighted average) with the result of hand calculation? However I don't know what is the equation should I use to calculate this average velocity at any cross section area in the domain. could you tell me about that equation?

Thanks you in advance.
Best Regards

I'd tend to put a surface at the position of interest and then run the report: why use maths when Fluent can give you a number?
