nennbs is on a distinguished road
These are my case blockMeshDic and problem being output as follows:

case blockMeshDic:

convertToMeters 1;

vertices
(
(0 0 0)
(0.1 0 0)
(0 0.1 0)
(0 0 1)
(0.1 0 1)
(0 0.1 1)
);

blocks
(
hex (0 1 4 3 2 2 5 5) (20 200 20) simpleGrading (1 1 1)
);

edges
(
arc 1 2 (0.0707107 0.0707107 0)
arc 4 5 (0.0707107 0.0707107 1)
);

boundary
(
down
{
type symmetryplane;
faces
(
(0 1 4 3)
);
}
left
{
type symmetryplane;
faces
(
(0 3 5 2)
);
}
curve
{
type patch;
faces
(
(1 2 5 4)
);
}
inlet
{
type patch;
faces
(
(0 1 2 2)
);
}
outlet
{
type patch;
faces
(
(3 4 5 5)
);
}
);

mergePatchPairs
(
);


Problem:

Create time

Check topology
