Can anyone help with cyclic BC???
I am trying to use cyclic BC on inlet and outlet for a case with dynamic mesh (wind over waves). The mesh does not move/change at the outlet and inlet patch and therefore I thought it could be possible to use cyclic conditions. I am running the case for a short time (I use pimpleDyMFoam) and then I am changing the patches to cyclic (by the use of foamUpgradeCyclic). Not sure if this will work but it looks like the syntax is accepted but I get a more fundamental problem about the pressure? I get this error message and it is related to set a reference cell for p. Anyone know a “work around”? --> FOAM FATAL IO ERROR: Unable to set reference cell for field p Please supply either pRefCell or pRefPoint file: /import/br1raid6a1h2/stud/sirik/pimpleDyMFoam.onewave/w2_su_cyclic2/system/fvSolution::PIMPLE from line 70 to line 72. From function void Foam::setRefCell ( const volScalarField&, const volScalarField&, const dictionary&, label& scalar&, bool ) in file cfdTools/general/findRefCell/findRefCell.C at line 115.

In your fvSolutions you should find something like:
PIMPLE { nCorrectors 2; nNonOrthogonalCorrectors 0; pRefCell 1000; pRefValue 0; } Apparently at least your entries for pRefCell and pRefValue are missing. Regards! |
