[FLASH-USERS] Thin targets in LaserSlab

[Graeme Scott - UKRI STFC]

Hi Norbert,


Thanks very much for getting back to me so quickly, and you were absolutely spot on, this is exactly what I was doing, so I've adjusted this in my .par file and everything looks good now.


Thanks again!

Graeme

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?
