Eulerian multiphase simulation

      Hi,


      I am a novice with respect to multiphase simulation. I am doing a very basic 2 fluid simulation where one of them is non-Newtonian. 


      Since each of the phases has a different constitutive equation to solve, I figured Eulerian multiphase is the best way to go. 


      The interphase interaction is through Schiller-Naumann which is dependent on the relative velocity of both phases right?


      However, after I run the simulation, velocity of each phase is equal to the velocity of the mixture. That seems wrong!


      Can you tell me what I am doing wrong. Also, the relative velocity also is the same as the velocity of the mixture.


      Thanks

      1/Yes.


      2/Means very very high drag if both velocities are almost the same


      3/Screenshots of your model setup are necessary here
