I am a newer in potentialFoam. Could you please let me know whether the following understandings are correct:

The potentialFoam solves the laplacian equation
laplacian(p)=0, in which p is the velocity potential.

However, in the source code potentialFoam.c and the initial field
the dimension of p is (0,2,-2,0,0), which stands for the "density normalized" pressure p/density.

the unit in the pEqn

left hand side:
fvm::laplacian(dimensionedScalar("1", dimTime/p.dimensions()*dimensionSet(0, 2, -2, 0, 0), 1), p)

laplacian dimTime/p.dimensions()*dimensionSet(0, 2, -2, 0, 0), 1) p
(1/m2 ) s m2/s2

which is 1/s

right hand side

fvc::div(phi)

div phi
1/m m3/s

which is m2/s


This means the unit is not consistent???!!!


can anyone tell me what's wrong with my understanding? thanks.
