Dear Seyit,
What version of FLASH are you using? If you are using version 3.0 or
above then you can refine up to 50 levels.
I don't think FLASH supports specifically what you are asking for. You
could try just keep the computational domain as it is, derefine in the
regions where you are not interested and refine in the region where you
are interested. An advantage of doing this is that the original
boundary conditions in your refined regions will be preserved. A
disadvantage is that the floating point computations may loose
accuracy.
Best,
Kevin Olson
