Understanding of potentialFoam's pressure equation

Hello, OFers!

I have read about the wiki page describing about the solver of potentialFoam at :http://openfoamwiki.net/index.php/PotentialFoam

the pressure equation for potential flow is http://openfoamwiki.net/images/math/...e5189b1328.png, but the implementation of the potentialFoam is as follows:

Code:

 

00059         fvScalarMatrix pEqn

00060         (

00061             fvm::laplacian

00062             (

00063                 dimensionedScalar

00064                 (

00065                     "1",

00066                     dimTime/p.dimensions()*dimensionSet(0, 2, -2, 0, 0),

00067                     1

00068                 ),

00069                 p

00070             )

00071          ==

00072             fvc::div(phi)

00073         );

00074

why it is not as the equation described in the wiki page? and how to dervie this equation?

Nobody could help me? or my question is too stupid?:confused:

There is a similar question, maybe this helps:

Might help the documentation updated 10 years after your question? :)
