Mr. CFD is on a distinguished road
I was wondering, what is the correct way to specify the flow rate in the injections panel of Fluent for a group injection? When it starts iterations, it prints to the screen "Injecting 'x' particles with mass 'm' at t='time' " (where x, m, and time are numbers that depend on your settings, of course). Should the mass 'm' be the total mass of all the particles being injected, or mass of a single particle, or of a single stream? Its a little ambiguous to me, and I want to be sure I'm setting it correctly.
