abt VOF
 

hi in my case, the flow is in-compressible at inlet, in between it is mixture of incompressible and compressible,and at outlet it is again incompressible. can any one tell me , if iam using vof model to solve this problem, can i be able to declare inlet boundary as mass-flow inlet. i want to track the volume fraction of the gaseous phase during the problem at particular instant of time. waiting for quick reply.
