Hello Everyone...
I am very new to OF and trying to mesh a cylinder for Hagen-Poiseuille flow. I am getting error like:

FOAM FATAL ERROR:
face 7 in patch 0 does not have neighbour cell face: 4(19 20 24 23)
From function polyMesh::facePatchFaceCells(const faceList& patchFaces,const labelListList& pointCells,const faceListList& cellsFaceShapes,const label patchID)
in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 127.

Actually I tried to correct the order of points and still i got the same error..
Also, when i tried with "paraFoam -block", paraview opened and closed before showing anything.

How to rectify this..

blockMeshDict is :
convertToMeters 0.1;
