Hello

I am new to foam, so my apologies if some of these questions are trivial

1)I am trying to get a reference for the density based solver used in rhoSonicFoam. I have only written Euler solvers previously, and have looked in Hirsch. Where could i get more information on this technique and it's implementation in OpenFoam?

2)Is it possible to get integrated quantities like Drag, lift etc?

3)Does OpenFoam have integration routines? Also how can i access the solution of rhoSonicFoam, and get all the variables like rho,p,U etc at all spatial locations?

Regards
Srinath
