Hi Foamers,
I have a question about pressure equation in icoFoam . we know pressure equation in icoFoam is as below : (according to Prof.jasak's thesis) In the source code we have : Code:
fvm::laplacian(rUA, p) == fvc::div(phi) what is the relation between this term and divergence of flux (phi) ? I appreciate any help from you, Thanks and best regards, Sasan. |

Hi Cyprien ,
Thanks for your reply But I didn't find my answer in meaning of HbyA . I think the pressure term should drop for getting this relation. Can you explain more ? about this trick ? Thanks and best regards, Sasan. |
