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.

convertToMeters 1;

    }

        type symmetryPlane;
        faces
        (

        );
    }

    doorin
    {
        type patch;
        faces
        (

        );
    }
    doorout

        );
    }

);

The error message is the following.

Hello,

It seems you have changed the position of the Vertices.
