I want to view to equations solved in rhoSimplecFoam solver, but I have a problem.
In the rhoSimplecFoam.C file I found follow lines:
#include "UEqn.H"
#include "pEqn.H"
#include "hEqn.H"
and I guess that these lines response for equations. Am I right?

pEqn.H is in the same directory, so is looked at it and found follow:
fvc::div(phi)-fvm::laplacian(rho/AtU, p)
What AtU is? Or at least where can I find out abou it?
And where I can find other hEqn.H and UEqn.H files?

I would be glad if you answer something.
