Hello,

In operating conditions, please use outlet density as operating density. Since, this is used to eliminate the hydrostatic pressure effects of air. Yes, you can set outlet pressure to 0 Pa, provided the operating density is applied correctly and is non-zero. It is generally recommended to use outlet density in operating conditions to remove hydrostatic effects.
