A question about patches
Greetings all
I am trying to make a 3D mesh with blockMesh utility. I have found an example of cylinder mesh in this subforum. I have a question about patches.
The example mesh is as follows:
Code:
vertices
(
( 1.25 0.0 1.25) // Vertex fiveoclocksqb = 0
(-1.25 0.0 1.25) // Vertex sevenoclocksqb = 1
(-1.25 0.0 -1.25) // Vertex elevenoclocksqb = 2
( 1.25 0.0 -1.25) // Vertex oneoclocksqb = 3
( 1.76776695455285 0.0 1.76776695137989) // Vertex fiveoclockcb = 4
(-1.76776695455285 0.0 1.76776695137989) // Vertex sevenoclockcb = 5
(-1.76776695455285 0.0 -1.76776695137989) // Vertex elevenoclockcb = 6
( 1.76776695455285 0.0 -1.76776695137989) // Vertex oneoclockcb = 7
( 1.25 100 1.25) // Vertex fiveoclocksqt = 8
(-1.25 100 1.25) // Vertex sevenoclocksqt = 9
(-1.25 100 -1.25) // Vertex elevenoclocksqt = 10
( 1.25 100 -1.25) // Vertex oneoclocksqt = 11
( 1.76776695455285 100 1.76776695137989) // Vertex fiveoclockct = 12
(-1.76776695455285 100 1.76776695137989) // Vertex sevenoclockct = 13
(-1.76776695455285 100 -1.76776695137989) // Vertex elevenoclockct = 14
( 1.76776695455285 100 -1.76776695137989) // Vertex oneoclockct = 15
);
blocks
(
//square block
hex (1 0 3 2 9 8 11 10) (3 3 10) simpleGrading (1 1 1)
//slice1
hex (5 4 0 1 13 12 8 9) (3 3 10) simpleGrading (1 1 1)
//slice2
hex (1 2 6 5 9 10 14 13) (3 3 10)simpleGrading (1 1 1)
);
//create the quarter circles
edges
(
arc 4 5 (0.0 0.0 2.5)
arc 5 6 (-2.5 0.0 0.0)
arc 6 7 (0.0 0.0 -2.5)
arc 7 4 (2.5 0.0 0.0)
);
patches
(
patch outlet
(
(2 4(0 3 2 1))
(2 4(0 4 7 3))
(2 4(4 0 1 5))
(2 4(1 2 6 5))
(2 4(3 7 6 2))
)
My question is what are these 2 and 4 before (0 3 2 1) in the outlet patch?
(2 4(0 3 2 1))
these 2 and 4 have been repeated for all other patches?
Regards
