Shoutout for these wonderful slides! Sincere thanks to the developers!

I do wonder why the "Standard Practices" slides do not recommend using GAMG as a preconditioner for solving the pressure field in the incompressible, single processor case (see below).

Establishing such a guideline would help in establishing a framework for best linear solver practices in OpenFoam.

Any ideas?

Code:
    p
    {
        solver          PCG;
        preconditioner  
        {
           preconditioner      GAMG; 
           smoother            GaussSeidel;
           nPreSweeps          2; 
           nPostSweeps         2; 
           directSolveCoarsest yes;  
        }
        tolerance       1e-6;
        relTol          1e-6;
        minIter         1;
    }
