[blockMesh] Cannot create mesh due to errors in topology, exiting !

Kairo · November 24, 2016, 06:41

Hi, I'm relative new to OpenFOAM and trying to create a mesh.
The checkMesh says the mesh is ok, but when I try to run blockMesh I get the following error message:

Creating block mesh from
"/home/caelinux/Desktop/OpenFOAM/Eksamen/vonKarman/constant/polyMesh/blockMeshDict"
Creating curved edges
Creating topology blocks
--> FOAM Warning :
From function bool Foam::blockMesh::blockLabelsOK(...)
in file blockMesh/blockMeshCheck.C at line 179
out-of-range point label 92 (max = 47) in block 9
Creating topology patches

--> FOAM FATAL ERROR:
Cannot create mesh due to errors in topology, exiting !

From function blockMesh::createTopology(IOdictionary&)
in file blockMesh/blockMeshTopology.C at line 568.

FOAM exiting

Any help is appreciated, thank you

Hi,

please read http://www.cfd-online.com/Forums/ope...-get-help.html and provide a minimal example (blockMeshDict) that allows to reproduce the problem in order to maximize your chances to get useful help.

The tool checkMesh needs to be run after the mesher (in you case blockMesh) in order to check the newly created mesh for quality and consistency. Since blockMesh fails you're probably running checkMesh against a mesh that was created with a previous setup (before changes in blockMeshDict).
