Doesnbt have neighbor cells
 

hi
when i simulation a cube 6*6*6,i define the bottom (0 1 2 3),when i excute the blockmesh and it show bottom (0 1 2 3)doesn't have neighbor cells.my blockmesh.file follow:
arguments "/home/ivan/OpenFOAM/ivan-1.4/run/tutorials/rhoTurbFoam/building" off;

convertToMeters 1;

Hi Weihong What you are tol
 

Hi Weihong

What you are told, is that the first face (face no. 0) in patch 8 is wrong. It could either be wrong orientation, but in your case, I cannot see any block which include all the points (0 1 2 3).

The specific patch which cause problems is the wall patch in the very bottom after the empty patches.
