New droplet properties in 3.200

Joel

Hi all I know that 3.200 has been out for a while now but have only just started using droplets in it and all the new options have thrown me off somewhat. Specifically the mass flow rate option on the injection definition panel. Before you could just set a velocity of each droplet particle which was all fine and dandy but now with this mass flow rate thing im a little confused, which actually governs the droplet flow features as by setting diameter and velocity surely the code can calculate mass flow rate (as before) the other problem is that i am having trouble with convergence and want to make sure that my velocity and mass flow rate arent contradicting each other. Cheers (bit of a rambling question im sorry!) Joel
