--> FOAM FATAL ERROR:
Inconsistent number of faces between block pair 8 and 9

From function blockMesh::calcMergeInfo()
in file blockMesh/blockMeshMerge.C at line 221.


The body (23 2 26 47 0 1 24 25 ) can never be connected with others. How to handle this body?

Hi,

the error message says it all. First check the coordinates and the ordering of your vertices. Then check the discretization of adjoining blocks.

Please provide the whole blockMeshDict. This will make it much easier for others to look at your problem!

Hi there,

whenever you have faces matching eachother they must have the same number of cells otherwise you have to use the function mergepatchṕairs at the bottom of the blockmeshdict file. If you post the code it will be easier to give you a better answer,

Good luck.
