hi
when i simulation a cube 6*6*6,i define the bottom (0 1 2 3),when i excute the blockmesh and it show bottom (0 1 2 3)doesn't have neighbor cells.my blockmesh.file follow: arguments "/home/ivan/OpenFOAM/ivan-1.4/run/tutorials/rhoTurbFoam/building" off; convertToMeters 1; vertices ( (-3 -3 0) (3 -3 0) (3 3 0) (-3 3 0) (-3 -3 6) (3 -3 6) (3 3 6) (-3 3 6) (-39 -3 0) (-39 3 0) (-39 -3 6) (-39 3 6) (153 -3 0) (153 3 0) (153 -3 6) (153 3 6) (-3 -60 0) (3 -60 0) (-3 -60 6) (3 -60 6) (-3 60 0) (3 60 0) (-3 60 6) (3 60 6) (-39 -60 0) (153 -60 0) (153 60 0) (-39 60 0) (-39 -60 6) (153 -60 6) (153 60 6) (-39 60 6) (-39 -60 60) (153 -60 60) (153 60 60) (-39 60 60) (-39 -3 60) (-39 3 60) (-3 -60 60) (3 -60 60) (153 -3 60) (153 3 60) (-3 60 60) (3 60 60) (-3 -3 60) (3 -3 60) (3 3 60) (-3 3 60) ); blocks ( hex (24 16 0 8 28 18 4 10) (36 57 6) simpleGrading (1 1 1) hex (28 18 4 10 32 38 44 36) (36 57 54) simpleGrading (1 1 1) hex (16 17 1 0 18 19 5 4) (6 57 6) simpleGrading (1 1 1) hex (18 19 5 4 38 39 45 44) (6 57 54) simpleGrading (1 1 1) hex (17 25 12 1 19 29 14 5) (150 57 6) simpleGrading (1 1 1) hex (19 29 14 5 39 33 40 45) (150 57 54) simpleGrading (1 1 1) hex (1 12 13 2 5 14 15 6) (150 6 6) simpleGrading (1 1 1) hex (5 14 15 6 45 40 41 46) (150 6 54) simpleGrading (1 1 1) hex (2 13 26 21 6 15 30 23) (150 57 6) simpleGrading (1 1 1) hex (6 15 30 23 46 41 34 43) (150 57 54) simpleGrading (1 1 1) hex (3 2 21 20 7 6 23 22) (6 57 6) simpleGrading (1 1 1) hex (7 6 23 22 47 46 43 42) (6 57 54) simpleGrading (1 1 1) hex (9 3 20 27 11 7 22 31) (36 57 6) simpleGrading (1 1 1) hex (11 7 22 31 37 47 42 35) (36 57 54) simpleGrading (1 1 1) hex (8 0 3 9 10 4 7 11) (36 6 6) simpleGrading (1 1 1) hex (10 4 7 11 36 44 47 37) (36 6 54) simpleGrading (1 1 1) hex (4 5 6 7 44 45 46 47) (6 6 54) simpleGrading (1 1 1) ); edges ( ); patches ( patch inlet ( (27 9 11 31) (37 11 31 35) (9 8 10 11) (11 10 36 37) (8 24 28 10) (10 28 32 36) ) patch outlet ( (25 12 14 29) (29 14 40 33) (12 13 15 14) (14 15 41 40) (13 26 30 15) (15 30 34 41) ) wall front ( (0 3 7 4) ) wall <back> ( (1 2 6 5) ) wall <left> ( (0 1 5 4) ) wall <right> ( (2 3 7 6) ) wall <top> ( (4 5 6 7) ) empty <wall> ( (24 16 18 28) (28 18 38 32) (16 17 19 18) (18 19 39 38) (17 25 29 19) (19 29 33 39) (26 21 23 30) (30 23 43 34) (21 20 22 23) (23 22 42 43) (20 27 31 22) (22 31 35 42) (32 38 44 36) (44 36 37 47) (47 37 35 42) (38 39 45 44) (44 45 46 47) (47 46 43 42) (39 33 40 45) (40 45 46 41) (41 46 43 34) (16 24 8 0) (0 8 9 3) (3 9 27 20) (17 16 0 1) (2 3 20 21) (25 17 1 12) (12 1 2 13) (13 2 21 26) ) wall <bottom> ( (0 1 2 3) ) ); mergePatchPairs ( ); // ************************************************** *********************** // could anyone help me? |

Hi Weihong
What you are told, is that the first face (face no. 0) in patch 8 is wrong. It could either be wrong orientation, but in your case, I cannot see any block which include all the points (0 1 2 3). The specific patch which cause problems is the wall patch in the very bottom after the empty patches. / Niels
