I have a closed system and after initializing, I patch temperature, species and volume fraction. The fluid is humid air and the condensation is supposed to happen. Initially all the fluid domain (chamber and inside the pipe) is mixture and no liquid phase. I patch 1 as volume fraction of that zone for mixture phase. when I plot the countor of pressure after initializing and patching, the pressure is zero at the fluid zone. But by patching I filled it with mixture (or not?) Should I patch pressure as well? It is transient simulation.

Remember pressure is against the operating pressure, assuming that's 101325Pa your domain is at atmospheric pressure at 0Pa.
