enzo-mrp-music/get_halo_initial_extent.py not working with yt 4.0.1
by C Bernhardt June 2, 2023

Dear yt users, I just updated yt to 4.0.1 and now I get this error message when trying to run enzo-mrp-music.py from John Wise on https://github.com/jwise77/enzo-mrp-music. Traceback (most recent call last): File "enzo-mrp-music/enzo-mrp-music.py", line 264, in <module> params = find_lagrangian_region(params) File "enzo-mrp-music/enzo-mrp-music.py", line 177, in find_lagrangian_region get_center_and_extent(params["halo_info"], File "enzo-mrp-music/get_halo_initial_extent.py", line 147, in get_center_and_extent halo_indices, halo_com, shifted = get_halo_indices(my_halo, final_dataset, File "enzo-mrp-music/get_halo_initial_extent.py", line 119, in get_halo_indices get_halo_sphere_particles(my_halo, dataset, radius_factor=radius_factor) File "enzo-mrp-music/get_halo_initial_extent.py", line 73, in get_halo_sphere_particles my_sphere = pf.h.sphere(my_halo_data['center'], radius_factor * r_200) AttributeError: 'EnzoDataset' object has no attribute 'h' I am honestly not sure what the attribute 'h' does in this case, so I didn't know what to try to adjust. Any suggestions for getting around this? Or how can I go back to yt 3? Kind regards, -- Carla Bernhardt PhD Student Universität Heidelberg ZAH Institut für Theoretische Astrophysik

Add particle filter in time series dataset
by HyeonYong Kim Jan. 26, 2023

Jan. 26, 2023

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 Jan. 5, 2023

Jan. 5, 2023

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!
