[FLASH-USERS] Two questions from a newbie, thanks!

Hi.
I worked on "spherical laser target" problem with very slightly tweaking in
LaserSlab simulation. All I had done is, just edit the "species" parameter
in Simulation_initBlock.F90 as 2D spherical target. (but I putted down this
problem in many reasons.)
I think the best way to explain to you is just show you!
my personal repository is : https://bitbucket.org/m13lue/flash-ptnd

I really hope that this files are helpful to you. :)
Best
