[yt-users] yt-users Digest, Vol 119, Issue 4

[Suoqing Ji]

Hi Kezman,

Judging from the spatial scale of the plots, I think there’s no zoom in here. Since I see there’s a sharp drop in density, my naive guess is either the blob is completely destroyed, or you lose tracking the blob (maybe due to deceleration).

My suggestion is that before tracking an individual blob, just plot the entire domain, then you’ll have a sense of what’s going on, and then you could determine the location of blob and track it easily.

Btw, you could also set origin=‘native’ (as you did previously), which will display the absolute coordinates in the plots and help to clarify the issue.

Let me know if it did not work!

Best wishes,
—

Plots for checkpoints 1 and 2 are fine but checkpoint 3 and others that follow are coming out as either extreme zoomed in or distorted. Any ideas how I might correct this?
