No. In fact ff3d deals with cartesian uniform grids (dx, dy and dz are 
constant) *or* unstructured grids of hexahedra.

There is no special optimizations/implementation for inbetween meshes...

By the way considering the geometry you sent here, it is possible that, in 
your case, the localization algorithm for unstructured hexahedra mesh in ff3d 
works...

I will try it and let you know...

I also have two questions:
- for this kind of geometry fictitious domain approximation should be exact: 
you holes can fit exactly mesh cells. Have you considered this approach?
- Why are hexahedra so important in that case?

Stéphane.
