[firedrake] Firedrake for CFD and multiphase

[Robert Sawko]

Hi,

I have been looking at Firedrake for some time and I finally sat down and
started working with your basic examples. I really like the high-level problem
specification and how it interfaces with solution procedure, but I need to ask
a few dull questions. The main purpose is to figure out the necessary effort to
make things work for my target problems. 

1) I've seen a number of mesh objects and I've seen CGNS, GMSH and Exodus. Are
these the supported mesh formats?

2) There's a firedrake-fluids repository on Github. Is there any active effort
in generic CFD for Firedrake? Are there people putting things like turbulence
models in Firedrake?

3) The problem I'd like to run is two-phase flow: oil drops in water in
periodic, box. For this I need phase advection, mass conservation and
Navier-Stokes with volume weighted density and viscosity. There is some
additional interface capturing skulduggery on top. Is there anyone who has
already tried to put something like this in Firedrake? Is there any obstacle
you foresee? 

I've already tried this problem with another generic code but finite volume low
order and I got stuck. Also performance portability would have been an issue
with this other code.

Please let me know,
Robert
