Cornell CS students seeking scientific software development projects
by Ariel Kellison 21 Jan '20

21 Jan '20

Greetings yt community, I am a graduate student in Cornell's Department of Computer Science seeking suggestions for semester long software development projects. I wonder, is there anyone in the yt community with a yt development project in mind that might benefit from a dedicated team of (aspiring) scientific software developers? The guidelines of the project require that we have a "client" to interface with on a weekly basis. To learn more about the course and the projects, see https://www.cs.cornell.edu/courses/cs5150/2020sp/ and follow the Projects links. Note especially that the projects are production systems, not prototypes or (purely) academic research. A project can be a small, complete system, or part of a larger system; students undertake projects in teams of 6 to 8. These teams develop real software applications for clients who intend to place them into production. At the end of the course, students are expected to hand over operational software, which has been thoroughly tested, with good documentation for future maintenance. Thanks for considering. Sincerely, Ariel Kellison

Issue with PLUTO slice plots
by g.r.kooij＠student.rug.nl 20 Jan '20

20 Jan '20

Hi all, I'm trying to make slice plots for 3D chombo data sets created with pluto version 4.3, but I'm consistently (not just this dataset) running into the issue where some boxes are empty. I've also made a slice plot using VisIt where these empty boxes do not show up, so it's probably an issue in yt. Is pluto v4.3 supported? Is there maybe an easy work around? yt-version: 4.0.dev0 The issue was also present in the latest stable version. The code to produce it is simple: fn = "data.0125.hdf5" var = 'density' fig = plt.figure() ds = yt.load(fn) p = yt.SlicePlot(ds, 'z', var) p.zoom(2) p.pan_rel((0.,-0.1)) p.set_zlim(var, 1, 2) p.set_cmap(field=var, cmap='rainbow') p.set_width((1., 1.5)) p.set_log(var, True) p.show() An image of the problem (red squares): https://i.imgur.com/llVsvn0.png data file: http://use.yt/upload/4a0db3c5 pluto.ini file: http://use.yt/upload/781478c2 Cheers, Richard

mass-weighted average magnetic field (QUIVERS) projected on to the plane plot
by nirmit sakre 05 Jan '20

05 Jan '20

I would like to annotate Mass weighted Magnetic field quivers on density projection plot so that i can display the magnetic field features. Do annotate_magnetic_field() , annotate_quiver() work correctly on projection plot or do they work only on slice plot correctly. If they work on projection plot then against which quantity magnetic field quivers are weighed or not weighted?
