Hi
I want to simulate a two stage brayton cycle with Aspen HYSYS V11 for H2 liquefaction plant.
So, I build a simple two stage example and run it. But, when I start it in dynamcis, it has a negative mass flow (seems like flow is reversed).
It looks good in steady state (with 204 g/s of helium). How can I fix it ??
This is my flowsheet and workbook
