Having different number of cells on the two neighboring patches is not an issue.
It sounds like you have one cell face that doesn't find any neighbor, that's an issue.
There are some parameters to...

Hi Maria and happy new year,
If your mesh deforms instead of "sliding" it probably means that the zones you are defining as rotating using the AMI algorithm do not correspond to the cylinders you...

How coarse is the baffle? The innerCycl...stl cell sizes are, I think, much too small. Is the baffle much coarser? Otherwise, trying making is coarser.
I'm not sure if this "Displacement points...

Hi Maria,
I have two further suggestions:
- try to do a much coarser mesh and see what happens (reduce all or most levels by 2 for example); do the same error messages appear?
-- doing so will...

Hi Maria,
It seems that the mesh has unacceptable non-orthogonality and skewness: did snappyHexMesh properly complete? Did it stop because it reached the maximum number of cells? If you can post...

Hi Theodore,
My experience is limited to GGI/AMI interfaces, so I can't comment on the MRF.
As for the outlet that allows incoming flow, I think you can use the inletOutlet boundary condition...

Hi Theodore,
If you change the direction of rotation of your fan, the flow direction should change. If it doesn't you might have boundary conditions that are too strong and impede proper flow...

Thanks to both of you for the feedback.
You mention GridPro and Pointwise and I'm curious to know whether you work directly with the generated mesh or manually edit it after generation ?
Also,...

I've ran into further problems when I was meshing a case where the spacing between the AMI interface and some of the surrounding walls is really small. I...

Hi Artur,
Thanks for sharing your expertise. I'm curious to know why you chose
a) minRefinementCells 100;
and
b) maxNonOrtho 95;
was it a trade off between a good snap and a good quality mesh ?...
