Coupling mixture model and phase field

Hi,

We are trying to couple mixture model and Laminar two phase flow, phase field method. But the initial values which I give in both the models doesn't match and the solutions doesn't progress.

As an alternative we performed simulation for capillary flow using phase field method. Then the velocity from the simulation was given as input to mixture model. But in mixture model we are not able to define interface.

Any suggestions would be helpfull for coupling these two physics.
