I need a 3D case file of wind flow over a tall building in OpenFoam.
I hope somebody can help me. |

you should have searched in the wiki http://openfoamwiki.net
http://openfoamwiki.net/index.php/Ma...banAreaNiigata http://openfoamwiki.net/index.php/Ma...ngInCityBlocks http://openfoamwiki.net/index.php/Main_ContribExamples if the examples from our friends in Japan do not help you you might search at the "wind energie" people or HVAC people stuff |

thank you elvis.
I went through the links you have given and tried some cases. But I used to shift from one to another when errors comes, which I was unable to rectify. Can you help me in one of the case I have downloaded and tried. The blockMeshDict file for the case is as given below. convertToMeters 1.0; vertices ( ( -0.4 0.28 0 ) ( -0.02 0.28 0 ) ( 0.02 0.28 0 ) ( 0.96 0.28 0 ) ( -0.4 0.02 0 ) ( -0.02 0.02 0 ) ( 0.02 0.02 0 ) ( 0.96 0.02 0 ) ( -0.4 -0.02 0 ) ( -0.02 -0.02 0 ) ( 0.02 -0.02 0 ) ( 0.96 -0.02 0 ) ( -0.4 -0.28 0 ) ( -0.02 -0.28 0 ) ( 0.02 -0.28 0 ) ( 0.96 -0.28 0 ) ( -0.4 0.28 0.392 ) ( -0.02 0.28 0.392 ) ( 0.02 0.28 0.392 ) ( 0.96 0.28 0.392 ) ( -0.4 0.02 0.392 ) ( -0.02 0.02 0.392 ) ( 0.02 0.02 0.392 ) ( 0.96 0.02 0.392 ) ( -0.4 -0.02 0.392 ) ( -0.02 -0.02 0.392 ) ( 0.02 -0.02 0.392 ) ( 0.96 -0.02 0.392 ) ( -0.4 -0.28 0.392 ) ( -0.02 -0.28 0.392 ) ( 0.02 -0.28 0.392 ) ( 0.96 -0.28 0.392 ) ); blocks ( hex (4 5 1 0 20 21 17 16) (29 19 59) simpleGrading (0.05 20 1) hex (5 6 2 1 21 22 18 17) (21 19 59) simpleGrading (1 20 1) hex (6 7 3 2 22 23 19 18) (73 19 59) simpleGrading (20 20 1) hex (8 9 5 4 24 25 21 20) (29 21 59) simpleGrading (0.05 1 1) hex (10 11 7 6 26 27 23 22) (73 21 59) simpleGrading (20 1 1) hex (12 13 9 8 28 29 25 24) (29 19 59) simpleGrading (0.05 0.05 1) hex (13 14 10 9 29 30 26 25) (21 19 59) simpleGrading (1 0.05 1) hex (14 15 11 10 30 31 27 26) (73 19 59) simpleGrading (20 0.05 1) ); edges ( /* arc 5 6 ( 0 0.02 0 ) arc 6 10 ( 0.02 0 0 ) arc 9 10 ( 0 -0.02 0 ) arc 9 5 ( -0.02 0 0 ) arc 21 22 ( 0 0.02 0.392 ) arc 26 22 ( 0.02 0 0.392 ) arc 25 26 ( 0 -0.02 0.392 ) arc 25 21 ( -0.02 0 0.392 ) */ ); patches ( wall walls ( (5 21 22 6) (6 22 26 10) (10 26 25 9) (9 25 21 5) ) patch inlet ( (4 20 16 0) (8 24 20 4) (12 28 24 8) ) patch outlet ( (3 19 23 7) (7 23 27 11) (11 27 31 15) ) wall sides ( (16 17 1 0) (17 18 2 1) (18 19 3 2) (12 13 29 28) (13 14 30 29) (14 15 31 30) ) wall lowerUpper ( (0 1 5 4) (1 2 6 5) (2 3 7 6) (4 5 9 8) (6 7 11 10) (8 9 13 12) (9 10 14 13) (10 11 15 14) (20 21 17 16) (21 22 18 17) (22 23 19 18) (24 25 21 20) (26 27 23 22) (28 29 25 24) (29 30 26 25) (30 31 27 26) ) ); mergPatchPairs ( ); Here we get a building that extends from bottom to top of the boundary. I need to change this geometry such that the building height must be reduced (top side of the building shouldn't touch the boundary) so that I can simulate a flow over the building. Can you show me how to change this case file for that ? thanks in advance. |
