[yt-users] Clump Finder Crashing

[Nicholas Earl]

Hey yt users,

I am getting some weird exiting happening with the clump finder and Ranger,
and I was wondering if anyone else has experienced the issue, or know what
I might be doing wrong? I see that it gets to a point where the min and max
densities are the same, but I didn't think it would cause the script to
crash...

Here is what I'm getting:

Finding clumps: min: 1.000000e-22, max: 1.000000e-21, step: 10.000000
> Wiping out existing children clumps.

I've also attempted lowering the step size to 5.0, but with the same
result. It also seems to be the case that I do not get this behavior when I
use function=True parameter, but I kept keeping jobs that would never end,
they would just be outputting Getting field Density from 1 the entire time.
So I've had to rerun the clump finder a few times, putting in some minimum
conditions, and still it'd happen.

Any ideas?

Thanks!
Nick
