Could anybody explain to me why in the tutorial (pitzDaily)of SimpleFoam solver, the dimensions of pressure is:
dimensions [0 2 -2 0 0 0 0];

But based on Henry's explanation

No pd = p - rho*(g.h) and you can calculate p from pd using this expression. Notice the dimension of pd:

dimensions [1 -1 -2 0 0 0 0];

h is the position vectors of the cell centres and g is the gravitational force vector.

I am confused by that.
If I need to use pressure as my inlet boundary, should I use Pd/rho? Thanks.
