Parallel mesh generation using snappyHexMesh
 
Hello, everyone!

I am sorry it may be a simple one, but let me ask you one question about mesh generation in parallel...
I am trying to solve a problem by myself, but I could not resolve.

Now I am studying the channelFoam tutorial (tutorial/incompressible/channelFoam/channel395)
and running it in parallel by using decomposePar.
For the next step, I would like to use snappyHexMesh for parallel mesh generation.
My blockMesh is the same as used in the channelFoam tutorial;

blockMesh
--------------------------------------------------
vertices
(
(0 0 0)
(4 0 0)
(0 1 0)
(4 1 0)
(0 2 0)
(4 2 0)
(0 0 2)
(4 0 2)
(0 1 2)
(4 1 2)
(0 2 2)
(4 2 2)
);

blocks
(
hex (0 1 3 2 6 7 9 8) (40 25 30) simpleGrading (1 10.7028 1)
hex (2 3 5 4 8 9 11 10) (40 25 30) simpleGrading (1 0.0984 1)
);
--------------------------------------------------

I would like to divide whole region (0:4,0:2,0:2) into four parts in parallel.
I heard that blockMesh does not support parallel operation (I am sorry if I guess wrong...),
but I am not sure how to describe the snappyHexMeshDict.
Hopefully, I would like someone to give me a hint what to do.

Thanks in advance!
