I'm a beginner in OF. I'm wondering whether this kind of grids below is valid for OF.
BTW, could someone tell me the name of this kind of grids? Thank you.

vertices
(
//vertex on the front
(0 0 0) // pt 0 (a0f)
(60 0 0) // pt 1 (a1f)
(120 0 0) // pt 2 (a2f)
(60 10 0) // pt 3 (a3f)
(120 10 0) // pt 4 (a4f)
(0 20 0) // pt 5 (a5f)
(60 20 0) // pt 6 (a6f)
(120 20 0) // pt 7 (a7f)

//vertex on the back
(0 0 1) // pt 8 (a0b)
(60 0 1) // pt 9 (a1b)
(120 0 1) // pt 10 (a2b)
(60 10 1) // pt 11 (a3b)
(120 10 1) // pt 12 (a4b)
(0 20 1) // pt 13 (a5b)
(60 20 1) // pt 14 (a6b)
(120 20 1) // pt 15 (a7b)
);

blocks
(
// block 1
hex (0 1 6 5 8 9 14 13)
cellZone (50 30 1) simpleGrading (1 1 1)

// block 2
hex (1 2 4 3 9 10 12 11)
cellZone (100 30 1) simpleGrading (1 1 1)

// block 3
hex (3 4 7 6 11 12 15 14)
cellZone (100 30 1) simpleGrading (1 1 1)
