Hello guys

I used my blockMesh for meshing before and i know that i have to match the cell number between adjacent face so i did it but open foam said

--> FOAM FATAL ERROR: (openfoam-2506)
Sub-division mismatch between face 1 of block 0(31 101) and face 0 of block 1(5 101)

It's my intension for different number between x cells because its not adjacent

I don't know what is the problem

I'm so confused

blocks
(
hex (3 19 18 2 4 20 29 13) (300 33 24) simpleGrading (5 0.3333 1)
hex (2 18 17 1 13 29 28 12) (300 4 24) simpleGrading (5 1 1)

hex (15 31 26 10 8 24 25 9) (300 33 28) simpleGrading (5 3 3)

when I used like this it worked but now it didn't work(yes its diffrent vertices and file)

please somebody help me

thank you
