Difficulty Merging Blocks
Hi all!
I'm new to OpenFOAM and have been trying to build my first test case. The geometry consists of a cylindrical inlet which opens into a larger cylindrical volume, which opens out to an even larger cylindrical volume. All three cylinders share the same major axis. Each cylinder makes up one block. I have been having problems with my blockMeshDict file when I define the walls of the larger cylinders which surround the inlet from the smaller cylinders. I have tried using MergePatchPairs to match things up with no success either. I have included my blockMeshDict file below. How should I be describing the back walls of the cylinders and the interface between each block?
Thank you all for your help!
Code:
FoamFile
{
version 2.0;
format ascii;
class dictionary;
object blockMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
