Hi guys,

I am trying to create a pipe using blockMeshDict. I need the pipe to be split into 3 blocks. But I am getting the following error:

--> FOAM FATAL ERROR:
face 1 in patch 0 does not have neighbour cell face: 4(5 6 12 9)

This is my blockMeshDict file. I still find writing my own mesh a bit tricky, could anyone give me a hand?

Thank you!

The combination (5 6 12 9) does not give you a proper face!

Draw your points and faces and you will realize it.

Cheers,
