Hi,

Thanks for sharing the updated figures.

a) Since the mass is not getting balanced - i'm suspecting it is mainly to do with the density calculation [Since your volume is constant (being a closed system)]. Could you share the density/pressure/temperature contours for any one of the case (at the begining, intermediate point before the mass imbalance starts to appear and the final contour at the point you stopped)

b) What was the choice of last species used in all your simulations ?
