hello everyone,
I'm solving the laminar flow around a flat plate at 4deg angle of attack with pimpleFoam. I got strange results, do you know where they might come from? case 102 nOuterCorrectors 3 nCorrectors 2 nNonOrthogonalCorrectors 2 Courant max = 0.5 case 104 nOuterCorrectors 6 nCorrectors 2 nNonOrthogonalCorrectors 2 Courant max = 10 case 106 nOuterCorrectors 6 nCorrectors 2 nNonOrthogonalCorrectors 2 Courant max = 5 The case 104, seems to be better than 102, because I added more nOuterCorrectors (but a very high Co) But in case 106, with the same correctors and half Co, again the flow field is totally weird... Any hint? |

Try much larger nOuterCorrectors and add residual control, see e.g. https://github.com/OpenFOAM/OpenFOAM...tem/fvSolution
(this is the only example in the tutorials using it, so don't care about the different solver rhoPimpleFoam) |
