Question

Has anyone solved the problem(2D) for flow over a pipe kept in between two infinitely large parallel plates. Inlet conditions : velocity-parabolic in one case and uniform in other case. I am getting "fatal error" when i run the blockmeshdict file.My file is: convertToMeters 0.1; vertices ( (14.142 -14.142 0) (14.142 14.142 0) (-14.142 14.142 0) (-14.142 -14.142 0) (-28.284 -28.284 0) (-28.284 28.284 0) (28.284 28.284 0) (28.284 -28.284 0) (28.284 -100 0) (-28.284 -100 0) (-1000 -100 0) (-1000 -28.284 0) (-1000 28.284 0) (-1000 100 0) (-28.284 100 0) (28.284 100 0) (1000 100 0) (1000 28.284 0) (1000 -28.284 0) (1000 -100 0) (14.142 -14.142 1) (14.142 14.142 1) (-14.142 14.142 1) (-14.142 -14.142 1) (-28.284 -28.284 1) (-28.284 28.284 1) (28.284 28.284 1) (28.284 -28.284 1) (28.284 -100 1) (-28.284 -100 1) (-1000 -100 1) (-1000 -28.284 1) (-1000 28.284 1) (-1000 100 1) (-28.284 100 1) (28.284 100 1) (1000 100 1) (1000 28.284 1) (1000 -28.284 1) (1000 -100 1) ); blocks ( hex(0 7 27 20 1 6 26 21)(40 80 1)simplegrading(0.5 1 1) hex(2 1 21 22 5 6 26 25)(40 80 1)simplegrading(0.5 1 1) hex(4 3 23 24 5 2 22 25)(40 80 1)simplegrading(0.5 1 1) hex(3 0 20 23 4 7 27 24)(40 80 1)simplegrading(0.5 1 1) hex(7 18 38 27 6 17 37 26)(1000 80 1)simplegrading(1 1 1) hex(6 17 37 26 15 16 36 35)(1000 80 1)simplegrading(1 1 0.5) hex(5 6 26 25 14 15 35 34)(40 80 1)simplegrading(1 1 0.5) hex(12 5 25 32 13 14 34 34 33)(1000 80 1)simplegrading(1 1 0.5) hex(11 4 24 31 12 5 25 32)(1000 80 1)simplegrading(1 1 1) hex(10 9 29 30 11 4 24 31)(1000 80 1)simplegrading(1 1 0.5) hex(9 8 28 29 4 7 27 24)(40 80 1)simplegrading(1 1 0.5) hex(8 19 39 28 7 18 38 27)(1000 80 1)simplegrading(1 1 0.5) ); edges ( arc 0 1 (20 0 0) arc 1 2 (0 20 0) arc 2 3 (-20 0 0) arc 3 0 (0 -20 0) arc 6 7 (40 0 0) arc 6 5 (0 40 0) arc 5 4 (-40 0 0) arc 4 7 (0 -40 0) arc 20 21 (20 0 1) arc 21 22 (0 20 1) arc 22 23 (-20 0 1) arc 23 20 (0 -20 1) arc 26 27 (40 0 1) arc 26 25 (0 40 1) arc 25 24 (-40 0 1) arc 24 27 (0 -40 1) ); boundary ( fixedWalls { type wall; faces ( (13 14 34 33) (14 15 35 34) (15 16 36 35) (10 30 29 9) (9 29 28 8) (8 28 39 19) (2 22 21 1) (1 21 20 0) (0 20 23 3) (2 3 23 22) ); } inlet { type patch; faces ( (13 33 32 12) (12 32 31 11) (11 31 30 10) ); } outlet { type patch; faces ( (36 16 17 37) (37 17 18 38) (38 18 19 39) ); } ); mergePatchPairs ( ); If anyone has solved this problem can you please share all the relevant files or correct mine.
