Reply To: (non-expected) gas fraction in cells near a wall

[Diogo Martinho]

The convergence looks okay, I let it run until the residuals are lower than e-7 only because I am tracking other parameters that are still converging though.
The value 2.111e+14 was just defined without any physical meaning. Just to ensure a high resistance to the gas phase in the middle domain. 
Velocity field looks like this (if I run the model without gas fraction)

 

And like this when defining gas fraction of 1e-6 at the inlets
