Hi all,
In simpleFoam.C, for example, I do not understand : 1/ What "adjustPhi(phi,U,p)" does? Can somebody summarize me quickly what it's done? 2/ According to the simple algo, I understand that the momentum equation is solved first, by guessing p. But when the boundary conditions for U are involved ? And i/ What does "p.boundaryField().updateCoeffs();"mean? ii/ Or "U.correctBoundaryConditions();"? Can somebody tell me where I have to look harder? Thanks in advance, Lam |
Short answer for where you sho
Short answer for where you should look harder is the source code. However, a more pleasant read (no offense) would probably be:

Hi guys,
I just follow your advice. Moreover, I had taken a look harder in the source code of "adjustPhi" I understand that adjustPhi(phi,U,p) keeps the continuity of the system, doesn't it? I mean for each face, the inlet flux = the outlet flux. So, in a discretized form: Sum[U_f * S_f] = 0. This what I understood for "adjustPhi". Hope that you will tell me if I'm wrong. But I still seek where the boundayconditions are involved. Cheers, Lam |
