Dear,
I'm an mechanical eng student with a first course on CFD in openfoam, and for an examination excercise i have to calculate the flow around 2 cillinders, diameter 2, distance 6. When trying to get the blockmesh to render, the same error was met time and time again, being face 0 in patch 0 does not have neighbour cell face. This occurs in the boundary part in cylinder 1 and 2. I have checked everything time and time again, even flipping the surfaces multiple times, with the same results. Any help? Thanks in advance! convertToMeters 1; vertices ( (-23 -25 0)//0 (23 -25 0)//1 (40 -25 0)//2 (-0.7071 -0.7071 0)//3 (0.7071 -0.7071 0)//4 (-0.7071 0.7071 0)//5 (0.7071 0.7071 0)//6 (-23 25 0)//7 (23 25 0)//8 (40 25 0)//9 (-23 -25 1)//10 (23 -25 1)//11 (40 -25 1)//12 (-0.7071 -0.7071 1)//13 (0.7071 -0.7071 1)//14 (-0.7071 0.7071 1)//15 (0.7071 0.7071 1)//16 (-23 25 1)//17 (23 25 1)//18 (40 25 1)//19 ); blocks ( hex (0 3 5 7 10 13 15 17) (30 15 1) simpleGrading (1 1 1)//0 hex (1 4 3 0 11 14 13 10) (30 15 1) simpleGrading (1 1 1)//1 hex (4 1 8 6 14 11 18 16) (30 40 1) simpleGrading (1 1 1)//2 hex (6 8 7 5 16 18 17 15) (30 15 1) simpleGrading (1 1 1)//3 hex (1 2 9 8 11 12 19 18) (15 40 1) simpleGrading (1 1 1)//4 ); edges ( arc 3 5 (-1 0 0) arc 5 6 (0 1 0) arc 6 4 (1 0 0) arc 4 3 (0 -1 0) arc 13 15 (-1 0 1) arc 15 16 (0 1 1) arc 16 14 (1 0 1) arc 14 13 (0 -1 1) ); boundary ( cylinder { type wall; faces ( (3 5 15 13) (5 6 16 15) (16 6 4 14) (4 3 13 14) ); } outlet { type patch; faces ( (2 9 19 12) ); } inlet { type patch; faces ( (17 7 0 10) ); } bottom { type symmetryPlane; faces ( (0 1 10 11) (1 2 11 12) ); } top { type symmetryPlane; faces ( (7 17 18 8) (8 18 19 9) ); } sides { type empty; faces ( (7 5 3 0) (7 8 6 5) (3 4 1 0) (8 1 4 6) (8 9 2 1) (18 17 15 16) (15 17 10 13) (14 13 10 11) (18 16 14 11) (19 18 11 12) ); } ); mergePatchPairs ( ); |
