I am still confused what cyclicAMI means, or why my model does not converge (see tips here
SimpleFoam convergence problems )


I use it for a compound mesh :

" Periodic (Cyclic) boundary conditions are very strong tool in CFD. Meshes of different elements can be inter-connected. The boundaries have to be of equal shape and equal area. The transformation can be rotational, translational or noOrdering. " https://www.cfdsupport.com/OpenFOAM-...t/node115.html


I would guess Cyclic Boundary Conditions are just: https://en.wikipedia.org/wiki/Period...ary_conditions


The use of the boundary condition at the interface of the angled mesh and the rectangular mesh seems okay.

I am able to get convergence here:

If I decrease the kinematic viscosity by 4 orders of magnitude from 0.2 to 2e-5 I am unable to find inputs in my fvSolutions file that lead to convergence.

My complete exploration from Meshing to the present modelling is available here:

I am having success with varying only p and U residuals for the kappa-epsilon model.
