[firedrake] Firedrake for CFD and multiphase

[George Ovchinnikov]

Hi Robert,

There is https://bitbucket.org/anriseth/oildrake package it does some
multiphase flow modeling, but I haven't tried it myself.

I'm interested in turbulence modeling myself, so if you will find
something useful, could you please share it?

Sincerely,
George
