Dear all,

I am new to blockMesh utility. I have attached my domain with corresponding vertices numbering. I want to divide my domain in to four as marked in the figure.
for that following codes are used:

hex(0 1 2 8 10 11 12 18) (10 10 1) simpleGrading (1 1 1) //block 0
hex(8 2 3 7 18 12 13 17) (10 10 1) simpleGrading (1 1 1) //block 1
hex(7 9 5 6 17 19 15 16) (10 10 1) simpleGrading (1 1 1) //block 2
hex(9 3 4 5 19 13 14 15) (10 10 1) simpleGrading (1 1 1) //block 3

But i am getting two internal face, its orientation is (7 17 9 19) and (9 19 3 13)

I want to get rid of this internal face. Or help me with any other condition that will nullify the effect of internal face.
