Hey everyone, My Enzo simulation has refined to enough levels that I need to make checkpoint dumps mid-timestep and do YT analysis from there. I can read in the checkpoint dump but when I go to find the max density I get this error: http://pastebin.com/2mNVxNyW Anybody have any idea what is going on and how to fix this? Also, since this dump is in the middle of the W-cycle, I believe the time on the finest grid is different then the root grid. How do I find the time on the finest grid for this checkpoint dump? Thanks. -- ------------------------------------------------------------------------ Joseph Smidt <josephsmidt@gmail.com> Theoretical Division P.O.
