Trying to model Fluid-on-Fluid interaction

Hi,

I'm trying to model the impingement of a high velocity fluid/gas onto a liquid surface (a molten pool of metal to be precise). Right now I'm working with the 'Laminar Two Phase Flow,tpf' module for this. I'm yet to understand many of the underlying physics, but I'm confused if this is the right type of physics node that should be chosen for this problem or is there a better way to model fluid-on-fluid interaction?

It's a simple 2-D problem where I want to see the deformation of the molten pool of metal due to the gas impingement from the top. Please suggest what I should do.

Thanks in advance.

Take a look at www.comsol.dk/showroom/gallery/1445/ and www.comsol.dk/showroom/gallery/177/

Thanks for the links. I had taken a look at those tutorials already, but still COMSOL is generating error messages in the time dependent solver. It says "Failed to find consistent initial values", but I've properly defined the initial values for both fluid domain. Here's the .mph file, hope someone can take a look and suggest something.
