Dear Foamers,

I want to learn/prepare a workflow for non-conformal mesh in OF. As a test case, I chose a 2D pipe (horizontal box) geometry. I created three meshes: meshA, meshB, and meshC, where one box ends and the next begins.

1. I changed boundary names in all meshes, and modified meshB number of cells to make the case non-conformal.
2. I then merged them into meshMaster, ending up with a case containing three regions (see the image at the end).
3. I attempted to turn the AMI patches into “cyclicAMI type” using createPatch. This is where I failed. (please see the createPatchDict file in meshMaster/system)

createPatch either failed or only operated on region0, while my case has three regions.

I uploaded the case files. You can run run.sh to reproduce my steps. I feel like I am missing something very trivial, but I’m stuck nonetheless.

Could you please help me or at least nudge me in the right direction?

Cheers,

Umut

Note: I dont think chtMultiRegion cases can be a good example, as I am only looking for a simple non-conformal workflow.

Soon after I asked the question, I found the solution. As I suspected it was very trivial, yet it cost me a day to find it.. ups. I'm sharing the solution hoping that no one needs it yet can find it here still.

Solution:
Instead of using createPatchDict, I used changeDictionaryDict
