Information about layer coverage

Hello guys,
I was wondering if there is a way to extract information about the percentage of layer coverage on a surface. In other words, I would like to get an indication like: ''Patch xx has 90% of its surface covered by layers.'' I am using snappyHexMesh as meshing tool. Any help would be highly appreciated. Thanks, Luca |

Hi Luca, at the end of the snappyHexmesh log you have a kind of table looking like this: Code:
patch faces layers overall thickness [m] [%] ----- ----- ------ --- --- w_walls 104424 9.46 0.0187 97.4 Doing final balancing --------------------- Writing 988052 added cells to cellSet addedCells Writing 883923 faces inside added layer to faceSet layerFaces Writing fields with layer information: nSurfaceLayers : actual number of layers thickness : overall layer thickness thicknessFraction : overall layer thickness (fraction of desired thickness) Layer mesh : cells:10417638 faces:31685237 points:10864745 Cells per refinement level: 0 96644 1 140357 2 183841 3 285012 4 541401 5 1370680 6 4468511 7 3331192 Writing mesh to time 3 Wrote mesh in = 718 s. Layers added in = 717.96 s. Checking final mesh ... Checking faces in error : non-orthogonality > 82 degrees : 0 faces with face pyramid volume < 1e-13 : 0 faces with concavity > 75 degrees : 0 faces with skewness > 4 (internal) or 20 (boundary) : 0 faces with interpolation weights (0..1) < 0.02 : 0 faces with volume ratio of neighbour cells < 0.01 : 0 faces with face twist < 0.02 : 0 faces on cells with determinant < 0.001 : 0 Finished meshing without any errors Finished meshing in = 731.81 s. End Finalising parallel run I use the line: Code:
patch faces layers overall thickness [m] [%] ----- ----- ------ --- --- w_walls 104424 9.46 0.0187 97.4 and compare the number of layers ( 9.46 in th is case ) t othe number I asked ( 10 in my case) I hope it help. Cheers fred |
