 May 8, 2011, 13:23 simple mesh with arcs #1 New Member   Mike Join Date: May 2011 Posts: 19 Rep Power: 15 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: https://docs.google.com/leaf?id=0Bw0...thkey=CIG149MM
