October 14, 2020, 13:40	Mass Flow Inlet vs Velocity Inlet	#1
minox101 New Member andrew spiteri Join Date: Aug 2019 Posts: 3 Rep Power: 6	Why does a simulation work with velocity inlet as air but then it goes crazy when applying a mass flow inlet ? I am using a VOF model and when I apply Mass flow inlet the simulation goes from a drag of 4 n to 5000+ n
