simple mesh with arcs
 

Hi, I am trying to create a simple mesh using blockMesh utility, like this one:

https://docs.google.com/leaf?id=0Bw0...thkey=CIWG25EF



The problem is, that when I type "checkMesh", it gives out 3 errors, as shown here:

https://docs.google.com/leaf?id=0Bw0...thkey=CNHAj8MB

But I can't figure out what the problem might be. Does anybody have an idea?

Thank you!

ps: this is the blockMeshDict file that I used:

Hello Mike,

I've just divided yours geometry into two blocks and everything works fine.

Sorry because I changed numbering of your original geometry.
