 July 12, 2012, 21:45 How to use blockMesh to generate cylindrical T-junction #1 New Member   Bin Xu Join Date: Apr 2012 Location: Singapore Posts: 23 Rep Power: 5 Hi Forums, I am new to OpenFOAM. I am struggling to use blockMesh to generate cylindrical T-junction geometry. Can anyone give clue or can post a simple blockMeshDict file that is two cylinder with same diameter then intersect to form a T-junction? Many thanks

If you have done it already perhaps you can guide me, convertToMeters 0.001; vertices ( (0 0 0) // point 0 (0 0 60) // point 1 (0 0 -60) // point 2 (0 60 0) // point 3 (0 -60 0) // point 4 (1500 0 0) // point 5 (1500 0 60) // point 6 (1500 0 -60) // point 7 (1500 60 0) // point 8 (1500 -60 0) // point 9 (690 0 60) // point 10 (810 0 60) // point 11 (750 60 60) // point 12 (750 -60 60) // point 13 (750 0 750) // point 14 (690 0 750) // point 15 (810 0 750) // point 16 (750 60 750) // point 17 (750 -60 750) // point 18 ); blocks ( hex (1 3 2 4 6 8 7 9) (20 20 1) simpleGrading (1 1 1) hex (11 12 10 13 16 17 15 18) (20 20 1) simpleGrading (1 1 1) ); edges ( arc 1 3 (0 30 50) arc 3 2 (0 30 -50) arc 2 4 (0 -30 -50) arc 4 1 (0 -30 50) arc 6 8 (0 30 50) arc 8 7 (0 30 -50) arc 7 9 (0 -30 -50) arc 9 6 (0 -30 50) arc 11 12 (50 30 0) arc 12 10 (-50 30 0) arc 10 13 (-50 -30 0) arc 13 11 (50 -30 0) arc 16 17 (50 30 0) arc 17 15 (-50 30 0) arc 15 18 (-50 -30 0) arc 18 16 (50 -30 0) ); boundary ( fixedWalls { type wall; faces ( (1 2 3 4) (6 7 8 9) (15 16 17 18) (1 3 6 8) (3 2 8 7) (2 4 7 9) (4 1 9 6) (11 12 16 17) (12 10 17 15) (10 13 15 18) (13 11 18 16) ); } ); mergePatchPairs ( ); // ************************************************** *********************** //

I just use GID to generate mesh and then import to OpenFOAM. Can you give a schematic illustration about your geometry and the location of each point? Best regards
