The dam break case is a tutorial for the interFoam solver, which works for two fluids (e.g. water and air). If you want another, third fluid, you will need a different multiphase solver.

Thank you for the reply.

But, instead of air i want to place another fluid which has density little less than water at the bottom of it. How to do that?
I am talking of two fluids water and say oil.

Vivek

look in tutorials/multiphase/multiphaseInterFoam/laminar/damBreak4phase

there is an example how to set up OpenFoam for four phases
I have not tried to make it three, maybe this is possible as well.

Best
Wouter
