balkrishna is on a distinguished road
When I run blockMesh i get the following warning :

Code:

    negative volume block : 2, probably defined inside-out
which translates to the following error when i run simpleFoam

Code:
--> FOAM FATAL ERROR: 
This mesh contains patches of type empty but is not 1D or 2D
    by virtue of the fact that the number of faces of this
    empty patch is not divisible by the number of cells.

    From function emptyFvPatchField<Type>::updateCoeffs()
    in file fields/fvPatchFields/constraint/empty/emptyFvPatchField.C at line 150.

FOAM exiting
Kindly help me with overcoming this error ... .
