Hello everyone,


I am trying to mesh a very simple shape that involve three different hexes. I set the blockMesh file and run it, but i am dealing with an error message that dont let me obtain my shape.
My blockMeshDict is the following.
Code:
convertToMeters 1;

vertices
(
    (0 0 0)
    (0 3.7 0)
    (1.11 3.7 0)
    (1.11 0 0)
    (0 0 0.54)
    (0 3.7 0.54)
    (1.11 3.7 0.54)
    (1.11 0 0.54)
    (1.11 3.31 0)
    (19.34 3.31 0)
    (19.34 0 0)
    (1.11 3.31 0.54)
    (19.34 3.31 0.54)
    (19.34 0 0.54)
    (19.34 3.7 0)
    (21.74 3.7 0)
    (21.74 0 0)
    (19.34 3.7 0.54)
    (21.74 3.7 0.54)
    (21.74 0 0.54)
);

blocks
(
    hex (0 1 2 3 4 5 6 7) (11 37 5) simpleGrading (1 1 1)
    hex (3 8 9 10 7 11 12 13) (182 33 5) simpleGrading (1 1 1)
    hex (10 14 15 16 13 17 18 19) (24 37 5) simpleGrading (1 1 1)
);

edges

boundary

    box
    {
        type wall;
        faces
        (
            (0 1 2 3)
            (3 8 9 10)

            (2 6 8 11)
            (14 17 9 12)      
        );
    }
    symmetry
    {
        type symmetryPlane;
        faces
        (
            (4 5 18 19)       
        );
    }

    doorin
    {
        type patch;
        faces
        (
      (0 1 4 5) 
        );
    }
    doorout
    {
        type patch;
        faces
        (
          (15 16 18 19)  
        );
    }

);

mergePatchPairs

);
The error message is the following.
