[FLASH-USERS] [EXTERNAL] Nonuniform Initial Temperature

[Marissa B. P. Adams]

Hi Nick,

Depends what you want to do. if you want to change the initial temperature of the target, e.g. sim_teleTarg = 58923704912948201e12 then you can simply just do so in the flash.par file and run as expected.

However say you would like to initialize a gradient in the target. This would require you to go into the associated file, Simulation_initBlock.F90 and initialize to your desires there. Then you go through the same sort of process as you did to obtain the executable and run the executable. 

Effectively the difference lies between whether or not the current set up is satisfactory and you just need to tune the given parameters, or you may want to do something that requires developing your own problem module (based off of the laser slab provided example problem).

I hope that makes sense.

Best,
Marissa

However, since the LaserSlab example defines the temperature by sim_teleTarg = 290, I’m not really sure how to expand that to a more complicated case, and I couldn’t find the relevant information in the use guide. If you could help, or point me to where I could find out more, that would be great.
