[FLASH-USERS] Question about grid size

[Robert Fisher]

Hi Malia :

  I presume you mean 512^2 uniform (as opposed to adaptive) resolution.
512^2 is a fairly low resolution, equivalent to 64^3 in 3D, and with fewer
than one million cells in total. You should be able to easily achieve it on
most problems even on a laptop on a uniform grid by adding the options "-2d
+ug --nxb=256 --nyb=256 -auto" to your setup command line, and adding the
following lines to your flash.par file :

iProcs = 2  #num procs in i direction; resolution NXB * iProcs
jProcs = 2

Finally, you can execute on 4 processes : "mpirun -np 4 flash4".

  Best wishes,

  Bob
