Hello everyone,
I am trying to perform a simulation about two cars passing by each other. Please find attached picture about the mesh. so there are two cubes standing for two cars. Iblock and oblock, containing the two cars(cubes), will move towards each other. So, interfaces between iblock and oblock is defined as ggi. I used the tutorial turboPassengeRotating. I run " setSet -batch setBatch regionCellSets setsToZones -noFlipMap" there is no error. then i run decomposePar, OF didn't abort, but there is some information like :"Processor 0: field transfer Initializing the GGI interpolator between master/shadow patches: interfacei/interfaceo From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /bb/civ/liuyu/OpenFOAM/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 544 Uncovered faces found. On master: 120 on slave: 120 Processor 1: field transfer Initializing the GGI interpolator between master/shadow patches: interfacei/interfaceo From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /bb/civ/liuyu/OpenFOAM/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 544 Uncovered faces found. On master: 120 on slave: 120 Processor 2: field transfer Initializing the GGI interpolator between master/shadow patches: interfacei/interfaceo From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /bb/civ/liuyu/OpenFOAM/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 544 Uncovered faces found. On master: 120 on slave: 120 Processor 3: field transfer Initializing the GGI interpolator between master/shadow patches: interfacei/interfaceo From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /bb/civ/liuyu/OpenFOAM/OpenFOAM-1.6-ext/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 544 Uncovered faces found. On master: 120 on slave: 120 End." Could anyone tell me, Does "uncovered faces found" mean, the mesh or GGI setting is not right? If you look at my geometry, you would find that interfacei and interfaceo don't match each other totally, so there should be "uncovered faces"? or not? Please help! Aqua |
