Hi
In icoFoam we have: Code:
fvScalarMatrix pEqn ( fvm::laplacian(rAU, p) == fvc::div(phiHbyA) ); Code:
fvScalarMatrix pEqn ( fvm::laplacian(rAU, p) == fvc::div(HbyA) ); |

I changed it to
Code:
fvScalarMatrix pEqn ( fvm::laplacian(rAU, p) == fvc::div(HbyA) ); Code:
fvScalarMatrix pEqn ( fvm::laplacian(rAU, p) == fvc::div(PhiHbyA) ); Code:
fvc::div(HbyA):dimensions [0 0 -1 0 0 0 0]; internalField nonuniform List<scalar> 9(0.157469 -0.0674757 -0.487085 -0.960691 0.789192 0.715649 30.1762 0.258981 -30.5822); fvc::div(phiHbyA):dimensions [0 0 -1 0 0 0 0]; internalField nonuniform List<scalar> 9(-0.435688 -0.0982547 0.152804 -0.0448476 0.720155 -0.152663 28.2072 0.236062 -28.5848); |

Hi, check the p-U coupling section (2.7) in my Ph.D thesis. It will also give you some pointers to good material on this topic.
Link to the PhD thesis is provided in my user page at openfoamwiki.net: http://openfoamwiki.net/index.php/User:Santiagomarquezd Regards.
