ANN: Virtual short-form course on using yt the week of April 10, 2023
by Matthew Turk 28 Feb '23

28 Feb '23

Hi all, I'm writing to announce that the week of April 10, we'll have a short-form course streamed online on how to use yt. It will be live broadcast through Twitch and later uploaded to YouTube for on-demand viewing. The presentations will be staggered across several different times-of-day to accommodate viewers in different time zones and will initially cover materials drawn from the "yt Quickstart" notebooks, building to an in-depth exploration of a dataset. Each day will include time for Q&A and interactive discussions. The times for the workshop will be: - Monday, April 10: 12:00-14:00 CDT / 17:00-19:00 UTC - Tuesday the 11th: 8:30-10:30 CDT / 13:30-15:30 UTC - Wednesday the 12th, 15:00-17:00 CDT / 20:00-22:00 UTC - Thursday the 13th, 11:00-13:00 CDT / 16:00-18:00 UTC In the days leading up to the workshop I will post here with more information about joining the live stream, as well as a rough breakdown of what topics will be covered on which days. Best, Matt

Unable to use annotate_contour
by hyf＠stu.pku.edu.cn 07 Feb '23

07 Feb '23

Hi, everyone, I have tried to use the function annotate_contour after SlicePlot. Unfortunately, the program ends up with no error info (see the output below) and without output figures. When I move the annotate_contour part out and keep SlicePlot, there are output SlicePlot figures. Besides, my YT version is 4.0.5 Any suggestions will be appreciated! Best wishes, He Yifeng Here are the codes: name='v' slc=yt.SlicePlot(ds, 'z', name, width=((aa,'cm'),(bb,'cm')),center=([cc,dd,0.01],'cm')) slc.annotate_contour( ('boxlib',name), levels=5, factor=4, clim=(-1e2,1e2), label=True, plot_args = {"colors": "k", "linestyles": "solid"}, text_args = {"colors": "w"} ) slc.set_cmap(field=("boxlib", name), cmap="Rainbow") slc.save() Here is the output: yt : [WARNING ] 2023-02-08 13:15:49,770 Switching to symlog colorbar scaling. yt : [WARNING ] 2023-02-08 13:15:51,632 Plotting ('boxlib', 'v'): Both positive and negative values.

Export projection plots to ASCII
by Chris Jessop 07 Feb '23

07 Feb '23

Hi everyone, I have some density-weighted projection plots that I would like to export as ASCII. More specifically, I would like to export the x, y, and z positions and at each of those positions values for gas energy, density, and the 9 primordial species for example. I see there is a way to generate a 2d profile and then export that to a QTable but I am not sure that's what I'm looking for. I also can't get the script to work as it returns "ValueError: zero-size array to reduction operation minimum which has no identity " when trying to use: profile2d = source.profile( [ ("gas", "density"), ("gas", "temperature"), ], # the x bin field # the y bin field [("gas", "cell_mass")], # the profile field weight_field=None, ) Is there any method for what I'm trying to look for? Any help would be appreciated. Cheers, Chris

Add particle filter in time series dataset
by HyeonYong Kim 26 Jan '23

26 Jan '23

Hi all, I'm trying to run Rockstar halo finder on multiple snapshots to make a merger tree. I referred to this page(https://yt-astro-analysis.readthedocs.io/en/latest/halo_finding.html) and ran rockstar successfully. But what I want to do is running the halo finder with filtered particles. When I run rockstar with a single snapshot it is easy to add a particle filter, but when it comes to multiple snapshots, I couldn't do it. Is there any way to add a particle filter in time series dataset or run a halo finder with filtered particles? Thanks in advance! Hyeonyong

How are unrefined areas handled when plotting AMR data?
by Santiago Erazo Papagayo 05 Jan '23

05 Jan '23

Hi all, I’m wondering when I plot AMR data with a refinement level of say 3, how are the under-refined regions handled? My guess is interpolation/extrapolation but I haven’t been able to confirm this so I thought I’d ask. Thanks in advance!
