I am running a Multiphase Flow(Air and Water) over a boat. I think I am Making some mistake in physics criteria.
How to
1. Give boundary level separating air and water.
2. Give water and air velocity.
3. View the water velocity profile as it crosses through the boat.

I want to view the pattern created by the water as it moves over the boat.

Suggest me correct physics criteria, I think the mesh is fine. Should I run this simulation as a steady state or unsteady state?

It is a multiphase problem(air and water).
Initial velocity zero for both phase.
I want to run a simulation for 1m/s velocity of both phases and view wave pattern.

Please find the attachment. The residuals are converged, but I can't find the entire wave pattern. Give me some suggestions.

Hi sriram9127,

I am not a pro with multiphase flow, but stupid question:
you know that there is a tutorial in the userguide for this kind of Sim?

I did it several years ago and I think it was for unsteady Simulations, but maybe it helps!

Cheers
