Could someone explain me the difference between group injection ( with number of streams) vs surface injection? Will it influence the result? Does the number of streams matter? If I'm not mistaken one stream = one parcel. So is there a difference when I specify one stream with flow rate lets say 0.1 kg/s, and 1000 streams with the same flow rate ?
PS. I asked about the difference between group and surface injection, because Residuals behave differently with these both.
Thanks in advance!!
