Hello everyone,
I am trying to make a floating break water with triangle sides. I tried to make the geometry with blockMesh because I did not have boxes to make with topoSetDict.
However while I am running the blockMesh, I receive an error:

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 108 (max = 103) in block 2
Creating topology patches

Reading patches section


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


From function blockMesh::createTopology(IOdictionary&)
in file blockMesh/blockMeshTopology.C at line 468.

FOAM exiting
blockMeshDict.zip
I did check the points and blocks, but the error still exist!!!!
please find my enclosed blockMeshDict and help me through solving the error..
Thanks.

Hi,

The problem comes because you have commented out some of the vertices, yet continued to keep their index:

(7 -0.16 0.3)//62
(7.2 -0.16 0.3)//63
(7.2 -0.2 0.3)//64
(7.206 -0.2 0.3)//65
(7.206 -0.16 0.3)//66
(7.394 -0.16 0.3)//67
(7.394 -0.2 0.3)//68
(7.4 -0.2 0.3)//69
(7.4 -0.16 0.3)//70
(7.6 -0.16 0.3)//71
(7.4 0 0.3)//72
(7.4 0.04 0.3)//73
(7.2 0.04 0.3)//74
(7.2 0 0.3)//75

/*
  (7 0 0)//76
  (6 0 0)//77
  (-5 0 0)//78
*/

(-5 -0.16 0)//79
(6 -0.16 0)//80

/*
  (7.6 0 0)//81
  (15 0 0)//82
  (25 0 0)//83
*/

Essentially what you have marked as "//79" will actually be counted as "//76" because there is a commented out section in between.

The simplest way to solve this is to remove the comments and have all your 120 vertices (0-120) present in the vertices definition, but use only a few of them to create your blocks.

Alternatively, if you want to keep the commenting, then you would have to redo the index of the vertices, especially the ones after a comment block.

Cheers,
Antimony

Hi Antimony,

Thank you so much for your hint. My problem solved based on the way that you suggested and right now I can see my shape in paraview.

Best regards,
Shima.
