Hi all, Has anybody written a replacement for findinits? If you remember, this was a utility that took two outputs along with a region specification. The particles inside that region in the later output were located in the earlier simulation, and the minimum bounding box that they occupied was output on the command prompt. This was usually used for zoom simulations. If nobody has, I'll take a shot at it. Thanks! -Matt

Linked below is a script that does almost what you want. This script runs HOP at some low redshift, and identifies all the particles in the halo. Then it loops over earlier data dumps to figure out the minimum volume that encloses all these particles as a function of redshift. The output can be used with the evolving refinement region setting that I put in 2.0 courtesy of John Wise. You can base your nested grids on the box at the highest z. I hope this helps! http://paste.enzotools.org/show/957/ _______________________________________________________ sskory@physics.ucsd.edu o__ Stephen Skory http://physics.ucsd.edu/~sskory/ _.>/ _Graduate Student ________________________________(_)_\(_)_______________
Hi Stephen, Thanks very much, I will be happy to use and share this. Best, Matt On Thu, Jul 29, 2010 at 7:38 AM, Stephen Skory <stephenskory@yahoo.com> wrote:

Matt,
Thanks very much, I will be happy to use and share this.
I forgot to mention that this is assuming that you're going to re-center the high-res sim on this area of interest, at [xc,yc,zc]. _______________________________________________________ sskory@physics.ucsd.edu o__ Stephen Skory http://physics.ucsd.edu/~sskory/ _.>/ _Graduate Student ________________________________(_)_\(_)_______________
