Hello,
I'm trying to make a simulation of a laminar flow around a cylinder.
This is my blockMeshDict

// ************************************************************************* //

When i run blockMesh my terminal gives:
--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'vertices' on line 20 and ending at line 280"

file: /home/marco/OpenFOAM/marco-4.1/run/cylinder195/constant/polyMesh/blockMeshDict at line 280.

I checked multiple times but i don't find anything wrong and also my blockMeshDict file is 272 lines long.

Please, help me to figure out this.
Thanks.

I found the mistake. It was a simple typo. Thanks anyway!
