Hello,

I am trying to simulate the entrance of a polymer into a cavity (mould). I have defined an inlet and outlet. I am using interFoam to calculate the gamma function. For now, I am considering two Newtonian fluids (polymer / air).

My problem is that I don't know how to specify the BC at the inlet for the gamma variable. I would like to define a constant gamma value at the inlet (= 1.0, considering 1 polymer and 0 air). It is a constant source of gamma = 1.0. If I only specify the value at the inlet patch, the polymer is only dispersed in the cavity and this is not what I want.

Can anyone give me suggestions on how to overcome this problem?
Also if anyone is using OpenFOAM for similiar purposes, I would like to know. I can contribute with experimental validation and data.
