Hey Foamers,
i just tried the turbulentHeatFluxTemperature bc in the buoyantBoussinesqPimpleFoam tutorial case with OF-1.7.1. I exchanged all the kappaEff with alphaEff. Its reading all the files, starts the time loop and breaks up directly. i got a: --> FOAM FATAL ERROR: request for volScalarField unifrom from objectRegistry region0 failed available objects ot type volScalarField are do i need to add a field in createFields? Thought its ok, when i just add a value in the 0/T file ... Any suggestions? Thanks in advance! Sarah |

Dear Foamers,
can someone explain me why OF1.7 still uses HTML Code: - ghf*fvc::snGrad(rhok)*mesh.magSf() instead of HTML Code: fvc::interpolate(rhok)*(g & mesh.Sf()) as it was used in the previous version OF1.6. I do not understand why the gradient of the densitiy is used while in the equations I find in literature it has to be just the densitiy multiplied with the constant g. Can someone help me? Is this still a bug or do I overlook something? Also in the Wiki-Link http://openfoamwiki.net/index.php/Bu...sinesqPisoFoam they use the interpolated density instead of the surface normal gradient. |
