[FLASH-USERS] Possibility of restarting FLASH from a selected region

[Kevin Olson]

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
