Porting .ply files to Blender with colors?
by Jill P. Naiman Aug. 15, 2022

Aug. 15, 2022

Hi All, I was curious if anyone has had any luck porting .ply files generated with yt into Blender with colors? It seems to port in the surfaces just fine, but they are a uniform color. From what I can gather, Blender imports .ply files with face color instead of vertex so I tried the surf.export_ply routine with "face" instead of "vertex" for sample_type, but no luck ("vertex" doesn't work either). Let me know if I can provide any more useful info. Thanks for any help, -J

Stars on volume rendering

Hi all, Thanks for all your help over the last couple of days. One more question: - Can I plot particles on a volume rendered image? I have stars and I want to show where they are!

Variance in phase/profiles
by david collins April 11, 2020

April 11, 2020

Hi, Everybody! Does anyone out there have a technique for getting the variance out of a profile object? A profile object is good at getting <X> vs. B, I'd then like to get < (X - <X>)^2 > vs B. Matt and I had spittballed the possibility some time ago, but I was wondering if anyone out there had successfully done it. Thanks, d. -- Sent from my computer.

Problem when run yt dev in parallel on Blue Waters
by Pengfei Chen Aug. 23, 2016

Aug. 23, 2016

Hi all, I have trouble running yt in parallel on Blue Waters. I installed yt using miniconda, the version of yt is ~/miniconda/lib $yt version yt module located at: /u/sciteam/madcpf/miniconda/lib/python2.7/site-packages/yt-3.3.dev0-py2.7-linux-x86_64.egg The current version and changeset for the code is: --- Version = 3.3-dev Changeset = 90f900be7a36+ yt Then with miniconda/bin in PATH I installed mpi4py-2.0.0. But when I tried to make the following simple output in parallel, I get: import yt yt.enable_parallelism() from yt.utilities.parallel_tools.parallel_analysis_interface import\ parallel_objects, communication_system comm = communication_system.communicators[-1] print comm.rank, comm.size 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 ... When I run a similar code but with yt-2.x also on Blue Waters, I get what I expect: 7 16 15 16 6 16 9 16 11 16 8 16 0 16 4 16 ... I'm confused about it. Could anyone give me some suggestions please? Thanks, Pengfei

rockstar question
by Robert Thompson April 8, 2016

April 8, 2016

Hi yt users! I had two quick questions regarding yt’s Rockstar implementation. Within the data returned from the return_halos() method: 1) how would one determine parent/child relationship? 2) how would one determine which particles belong to which halo? The returned data has “num_p" and “p_start” variables, but I’m not sure if those indexes line up with the ordering in which I passed the particles in to the make_rockstar_fof() function. Thanks! -Robert Thompson

load spherical polar coordinate data with mesh refinement in HDF5
by Jiang, Yanfei April 5, 2016

April 5, 2016

Hi, I have some data from a new version of Athena simulations. It is in spherical polar coordinate with mesh refinement written in HDF5. The data structure is similar to flash data but not the same. Does anyone have suggestions to load such data to yt directly? Thank you. -- Yan-Fei Jiang Einstein Fellow Harvard-Smithsonian Center for Astrophysics 60 Garden Street, Cambridge MA USA 02138

Covering Grid Dimensions: multiple refinement levels
by Carla Bernhardt April 5, 2016

April 5, 2016

Dear YT Users, To better understand covering_grid (or smoothed_covering_grid), can someone explain what dimensions I should use when I have multiple levels of refinement? If I have 1 level of refinement from AMR data, the dimensions should be the same, I believe, but what if I have 2 or 3 levels of refinement? Should the fixed resolution region then have dimensions of dims*2^2 and dims*3^2 respectively? Here is one example from a tutorial <http://yt-project.org/doc/examining/low_level_inspection.html#examining-gri…> if that helps isolate my question: all_data_level_2 = ds.covering_grid(level=2, left_edge=[0,0.0,0.0], dims=ds.domain_dimensions * 2**2) Thanks in advance, Carla

Inclination problem
by Sushilkumar March 31, 2016

March 31, 2016

Dear Matt: Pleas correct me if I am wrong but "off axis slices" takes slices of the plot that is already plotted. However, I would like to plot my data in a new coordinate frame (x`,y`,z`) which is inclined at an angle of say alpha from the default (x,y,z) frame. Or I would like to plot my data in a rotated frame (x`,y`,z`), which is rotated at an angle of alpha from (x,y,z).

Inclination problem
by Sushilkumar March 30, 2016

March 30, 2016

Dear yt: I am trying to numerically solve the region around a pulsar. Now since pulsar is an inclined rotator with inclination angle between rotation axis and dipole axis I would like to include in my yt script. My original code written in FORTRAN incorporated this inclination but how would I incorporate it into my visualization using yt without changing my data. Could you suggest ways for the same? The google drive link to my script (streamline.py) and streamline plot (streamline_t000.png) is included https://drive.google.com/open?id=0B4g8shg4DL7oak5PLWVVdG5UMHc Thanks in advance On Tue, Mar 29, 2016 at 12:54 PM, <yt-users-request(a)lists.spacepope.org> wrote: > Send yt-users mailing list submissions to > yt-users(a)lists.spacepope.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org > or, via email, send a message with subject or body 'help' to > yt-users-request(a)lists.spacepope.org > > You can reach the person managing the list at > yt-users-owner(a)lists.spacepope.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of yt-users digest..." > > > Today's Topics: > > 1.
