Hi all... My name is maria and I have just started using STAR-CD. I am trying to set up a transient diesel injection case without evaporation using the huh atomisation model with variable flow rate and droplet breakup. All residuals are decreasing (of the order E-02) however the mass residual is either fluctuating very close to 1 or increasing. Does anyone have any suggestions...? thanks....

I don't understand the problem...you're running a transient simulation of an injection inside a chamber...and the residual of the computation don't go to "0" is it? Since it's a transient computation I think it's normal...am I wrong??? (I've just started too...)
