Hi there Foamers,
I am trying to improve my simulation using the mapped boundary condition on OF240. I found it on a tutorial Code:
$FOAM_RUN/incompressible/pisoFoam/les/pitzDailyMapped In my blockMeshDict file I defined it as Code:
boundary ( inlet //0 { type mappedPatch; offset (-20 0 0 ); sampleregion region0; sampleMode nearestCell; samplePatch none; faces ( ... ); } ... ) Code:
boundaryField { inlet { type mapped; value nonuniform List<vector> 90( ... ); interpolationScheme cell; setAverage true; average (1 0 0); } ... } Code:
--> FOAM Warning : From function mappedPatchBase::mappedPatchBase ( const polyPatch& pp, const word& sampleRegion, const sampleMode mode, const word& samplePatch, const vector& offset ) in file mappedPatches/mappedPolyPatch/mappedPatchBase.C at line 631 Did not find 90 out of 90 total samples. Sampling these on owner cell centre instead. On patch inlet on region region0 in mode nearestCell with offset mode uniform. Suppressing further warnings from mappedPatch Has anyone ever faced such mesage(s) using this b.c.? Any experienced Foamer? I looked at the code but I didn't really get why I am having this issue. Any help would be greatly appreciated. F. Soares |

Hi.
Actually I have not. I believe I just increased my inlet region before the step, which is not optimal but it was better than nothing. Anyway good luck. Mit freundlichen Grüßen, F. Soares. |

Hi,
Probably you wouldn't need the answer anymore. I had the same problem, and it was due to my rotated coordinate system. Whenever the offset vector is out of your domain you get this warning. In my case, my initial offset vector was (0 0 10) and I had to reverse its direction. I used (0 0 -10) and it worked just fine. |
