Hi,

I have a question related to the inlet boundary conditions for the Mixture Model, Laminar Flow interface.
As far as I understand I can only imposed a velocity or a pressure with no viscous stress (Mixture Boundary Condition) boundary condition at the inlet. With non-Newtonian flows it is actually more convinient to use a mass flow rate boundary condition - as it is possible to do with the standard Single-Phase interface.
Do you know if it possible to do the same also for this case? Perhaps adding an ODE that solves for the velocity profile?

Any suggestion is more than welcome,

Thanks,

J
