[FLASH-USERS] Thin targets in LaserSlab

[Norbert Flocke]

Hi Graeme,

Do you use lrefine_min = 1 as a starting resolution? If yes, then your 
traget thickness can only be as small as 1 cell side and this depends on 
the number cells per block. If you want thinner targets, then you probably 
must increase lrefine_min to a higher number, so that the LaserSlab 
simulation starts with smaller cells that can accommodate smaller targets.

Best,
Norbert

It seems that even when I increase the AMR to resolve tens of nanometres, that the target can only get as thin as about ~5 um, and when I try to make it thinner than this it disappears completely. I wondered if there's some configuration setting that's in the setup that's preventing me from getting thinner than this?
