Hi!

I'm trying to use terrainBlockMesher to mesh the complex terrain. I installed OF v.2.3.1. and there also terrainBlockMesher from GitHub.
I modified tutorial case and applied on my .stl file, but whenever I run terrainBlockMesher, first I get this:

And then it's normally running. After it creates polymesh and rest, if I checkMesh I get errors like this:

...and then it's checking topology, geometry, ...

Is the problem in the way I used terrainBlockMesher, or is the problem how it's installed? I'm sorry if the question is stupid, but can somebody explain me or give me maybe some hint what would these errors mean?

Cheers and nice day to all !

After mesh is generated, by running command checkMesh I get this:

Any idea what are those red coloured lines, how to fix it?

Hello Andela,
Did you finally find the solution for this warning messages.
I encountered similar problem.
