Dear foamers

I am trying to implement a wall model which is known as zonal (or layering or two-layer) RANS and LES method. Papers related to this model are below

1. Wang and Moin, Dynamic wall modeling for large-eddy simulation of complex turbulent flows, Physics of Fluids, 2002

2. L. Temmerman, M. Hadžiabdic, M.A. Leschziner, K. Hanjalic, A hybrid two-layer URANS–LES approach for large eddy simulation at high Reynolds numbers, International Journal of Heat and Fluid Flow, Volume 26, Issue 2, April 2005, Pages 173-190,

In these models, simplified RANS equations need to be solved in the 'inner' or 'embedded' mesh which is different from global mesh for LES (global mesh means that the mesh which is saved in /constant/polyMesh/ folder). So I am wondering is there any way to deal with two different mesh and equations at the same simulation with its overlap area (the inner mesh overlaps on the global mesh) in OpenFoam? I really don't know where to start. if there is any prototype case or any other approach to cope with this issue that you know, please let me know. and any other advice will be very grateful.
