water disappearing in my system

      HinnI am running a two phase (water and co2) flow transient simulation. the problem is that despite the fact that I have a liquid inlet (very low flow rate of 10e-6 kg/s), I cannot monitor presence of any liquid in my system (I am monitoring the mass of liquid in the system, phase fraction of liquid in various places and flow rate of liquid in various places and it is always zero. also the residuals are a flat line (while for a transient flow I was expecting a cyclic behaviour).nnbefore I was running the same simulation with a liquid flow rate 10 times higher and everything was normal (the residuals were cyclic and I could trace and even see the liquid in system.nnCould it be that I am making some mistake or the flow rate suddenly has decreased so low that it cannot be seen by ANSYS anymore!nFeel free to suggest me a way to solve this problem.

      If you go to report Volume integral and select mass than the water phase: what is reported?n

      Which multiphase model are you using, and what is the boundary set up? n
