[FLASH-USERS] RTFlame in FLASH4

[ugkarriraghunath at ug.iisc.in]

Hello everyone,

I am trying to simulate Rayleigh-Taylor instability in FLASH code. In  
Cartesian geometry I want to extend the domain size in x-direction so that
I can visualize the detonation in visit software. For that I am doubling
"xmax", "nblockx", "iprocs", so that the grid size "dx" remains constant.
But when I do so I am getting completely different results. For example,
the time of detonation which is at ~0.4sec when xmax=135e5 , nblockx=9,
iprocs=1 has changed to ~0.9sec when I put xmax=270e5, nblockx= 18 ,
iprocs=2 . Can someone please tell me where I am going wrong. This will be
very helpful to me.


Thank you in advance.


Raghunath.
