Hello I am new to the tool COMSOL. I am trying to get acquainted with the tool and trying to run a basic simulaiton for mass balancing for which I have taken a LAMINAR FLOW physics and STATIONARY study. My doubt is how I have to find the mass outlet in COMSOL because I am getting only the velocity and pressure profiles in the results.

Can please someone help me on this problem

Thanks in advance Sai Teja

In derived values node, select global evalaution and evaluate mass outflow.
Other option is to evlaute surface intergertion of (spf.rho * spf.U)
