Hi R,

- The navier stokes equation will now have a source term.

i need to calculate u,p,H (=cT), gl (liquid fraction) for each element. Iterating the energy equation to obtain convergence in the nodal liquid fraction value (source term) is one the key areas where I was having crisis situation.
So is it resolved?
If things get too complicated, try some simplifications so that we have some example(s) within SfePy for the GSoC final phase. I will be able to support you fully from 11.9.
The momentum and energy equations are coupled through both the buoyancy and the source term (Bu). The B depends on the liquid fraction which represents an extra unknown in the governing equations. Since the liquid fraction is updated such that the corection term becomes zero at the convergence of the enthalpy equation.
I tried searching the internet but could not find any FEM implementation is this field so I started developing a python solver from scratch in order to test the algorithm suggested in those papers using finite volume method, as at least I will have a solver ready to couple it with sfepy.
Ok, keep up the good work, and let us know about progress or problems. Once that solver works, you will have something to compare a new FEM solution with.
Cheers, r.

Hi Ankit,
it looks very interesting. Do you have also a weak formulation of the complete problem? I would like to see the form
Find u, p, ... such that ... holds for all v, q...
to see if all the terms are available. Or do you have already an initial implementation? I will be offline from 7. to 11.9. but Vladimir should be able to answer your questions. I am available today.
r.
