Using AMI without multi-region meshing

me3840 · May 28, 2017, 18:57

Hello folks,

I would like to use the AMI on a different mesh setup than all of the tutorials. For complex geometries I find that the multi-region meshing feature of snappyHexMesh is really unreliable. As an alternative, I mesh each region independently and combine them later.

The trouble here is, from what I can tell, the AMI setup using createBaffles can only be done with a conformal interface. The tutorials will split the baffles into two sides using mergeOrSplitBaffles after creating them. But for me, they are already split - but the createBaffles dictionary doesn't allow me to specify two faceZones, one for each side of the interface.

So how would I get around this? Anyone done something like this before?

Solution is easy, just make two AMIs and tell them they're each other's neighbor. Assign the slaves a dummy patch and it works.
