Fatal Error at blockMesh Generation - wedge
 
1 Attachment(s)
hey,
I'm wholy new to CFD-software and I'm trying to simulate a Rheometerflow (Plate/Plate) in 2D with OpenFOAM. I tried to use wedge-description for my problem, but blockMesh gives me some Errors, e.g. "face 0 in patch 0 does not have neighbour cell face: 4(3 2 4 3)"
the blockMeshDict is appended.
can you help me? thanks!

Hi

first of all you might consider to provide a valid blockMesh file which is
readable by a common text editor.

second the error message is self explaining:

Code:

face 0 in patch 0 does not have neighbour cell face: 4(3 2 4 3)"
in the very first patch you define the very first face doesn't have a neighbour
which is usually due to bad definition of the face (numbering not correct)
So check whether the numbers are in the correct order or if the belong to the right face.

To get a better insight typ:

paraFoam -block

and see your mesh in paraview and check it

regards
