Dear all,

recently I was involved in some CFD project which is going to be based on OpenFoam. Looking at the manuals and codes, it's obvious, that one has to write his own solver for more complicated / mixed problems.
For training and educational purposes I would like to write solver for incompressible flow where density = density(T).
I would greatly appreciate, if you point me in the right direction how to begin?
