Hi! Foamers,
I am trying to run overlapGgi and getting the error as: --> FOAM FATAL ERROR: Found uncovered faces for GGI interface innercylinder/outercylinder This is an unrecoverable error. Aborting. boundary blade_1 { type wall; nFaces 46561; startFace 5183059; } blade_2 { type wall; nFaces 39728; startFace 5229620; } innercylinder { type overlapGgi; nFaces 41878; startFace 5269348; rotationAxis (0 0 1); nCopies 30; shadowPatch outercylinder; zone innercylinder_faces; } outercylinder { type overlapGgi; nFaces 41880; startFace 5326982; rotationAxis (0 0 1); nCopies 30; shadowPatch innercylinder; zone outercylinder_faces; } farfield { type patch; nFaces 15756; startFace 5311226; } setBatch faceSet innercylinder_faces new patchToFace innercylinder faceSet outercylinder_faces new patchToFace outercylinder cellSet rotor new cellToCell cellRegion0 quit dynamicMeshDict dynamicFvMeshLib "libtopoChangerFvMesh.so"; dynamicFvMesh turboFvMesh;//mixerGgiFvMesh; turboFvMeshCoeffs//mixerGgiFvMeshCoeffs { coordinateSystem { type cylindrical; origin (0 0 0); axis (0 0 1); direction (1 0 0); } rpm { cellRegion0 360; cellRegion1 0.0; } slider { insidecylinder_faces 360; } } MRFZones cellRegion0//rotor { nonRotatingPatches (farfield); origin origin [0 1 0 0 0 0 0] (0 0 0); axis axis [0 0 0 0 0 0 0] (0 0 1); omega omega [0 0 -1 0 0 0 0] 360; } Command regionCellSets setSet -batch setBatch setsToZones -noFlipMap solverName Can any one tell me how to resolve this error. The figure shows blade1, blade2 and innercylinder. Thanks a lot. |

I solved the issue using ggi instead of overlapGgi.
The sample is given below: cylr { type ggi; nFaces 1656; startFace 9801445; rotationAxis (0 0 1); nCopies 30; shadowPatch cyls; zone cylr_faces; bridgeOverlap true; //This was also important. } cyls { type ggi; nFaces 1656; startFace 9829183; rotationAxis (0 0 1); nCopies 30; shadowPatch cylr; zone cyls_faces; bridgeOverlap true; } Thank you.
