 December 7, 2013, 07:36 Cylindrical Duct with blockMesh #1 New Member   Stefano Puggelli Join Date: Sep 2013 Posts: 4 Rep Power: 5 Sponsored Links Hi everybody, I am new of OpenFoam and I am trying to do a very simple geometry with blockMesh. I am trying to build an half of a cylindrical duct (180 degrees) and for this reason I divide my cylinder in 4 sector. I write my blockMeshDict and it works but automatically OpenFoam creates 3 default Faces corresponding to the divisions between the sectors and I don't understand why. I put here my blockMeshDict (there are only three sector in this version but the problem is the same. I feel a bit stupid asking so simple thing but any idea would be very appreciated. convertToMeters 0.001; vertices ( (0 0 0) (0 0 0) (0 5.2 0) (0 5.2 0) (-0.65 0 0) (-0.459 0 0.459) (-0.459 5.2 0.459) (-0.65 5.2 0) (0 0 0.65) (0 5.2 0.65) (0.459 0 0.459) (0.459 5.2 0.459) ); blocks ( hex (0 1 2 3 4 5 6 7) (50 45 1) simpleGrading (1 1 1) hex (0 1 2 3 5 8 9 6) (50 45 1) simpleGrading (1 1 1) hex (0 1 2 3 8 10 11 9) (50 45 1) simpleGrading (1 1 1) ); edges ( arc 4 5 (-0.60 0 0.248) arc 6 7 (-0.60 5.2 0.248) arc 5 8 (-0.248 0 0.60) arc 9 6 (-0.248 5.2 0.60) arc 8 10 (0.248 0 0.60) arc 9 11 (0.248 5.2 0.60) ); boundary ( inlet { type patch; faces ( (4 0 1 5) (5 0 1 8) //(8 0 1 10) ); } outlet { type patch; faces ( (6 2 3 7) (9 2 3 6) (11 2 3 9) ); } wall { type wall; faces ( (0 4 7 3) (1 2 9 8) ); } freestream { type patch; faces ( (8 5 6 9) (5 4 7 6) (10 8 9 11) ); } ); mergePatchPairs ( );
