Stars on volume rendering
by Elizabeth Harper-Clark 11 Dec '21

11 Dec '21

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! Thanks, Libby -- Elizabeth Harper-Clark MA MSci PhD Candidate, Canadian Institute for Theoretical Astrophysics, UofT Sciences and Engineering Coordinator, Teaching Assistants' Training Program, UofT www.astro.utoronto.ca/~h-clark <http://www.astro.utoronto.ca/%7Eh-clark> h-clark(a)cita.utoronto.ca Astronomy office phone: +1-416-978-5759

Variance in phase/profiles
by david collins 11 Apr '20

11 Apr '20

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.

Matt, Sam, Eric, Britton, Thank you for all the previous infos (projections and 2D profiles). Now I have a clearer vision of these features. Sam, you are right, the derived field is created before the radial binning.I will let you know if I have further doubts (for sure). As I said to Matt previously, I want to extend my congratulations to all the YT developers.You are doing a great job. Cheers, Max

scale on colourbar?
by Elizabeth Tasker 12 Jun '12

12 Jun '12

Hi, I'm creating a slice image but it's refusing to tick mark my colour bar properly: http://i.imgur.com/YQBWJ.png pc = PlotCollection(pf, center=position) p = pc.add_slice("NegEscapeVelocity", 2, field_parameters={"disk_vector":disk_vector, "disk_center":disk_center, "disk_radius":profile["DiskRadius"], "disk_potential":profile["PotentialField"]}) p.set_log_field(False) p.set_zlim(0.0, 30.0) p.set_width(8, 'kpc') Is there something simple I've done wrong? I tried rearranging the last 3 lines, but to no avail! Elizabeth

removing region
by Geoffrey So 31 May '12

31 May '12

Is there a way for yt to say, to remove a certain cells from an 3D object, say removing a small sphere from a big sphere or cube? I guess cut_region() isn't the one. From G.S.

frb & covering grids
by Elizabeth Tasker 30 May '12

30 May '12

Hi, I want to make a uniform 2D grid of a field from my Enzo simulation data. Currently, I take a slice: sl = pf.h.slice(0, 32.0, 'Accel3Name') and then make an frb: frb = sl.to_frb(64.0/pf['kpc'], resolution, center=galaxy_center) However, it looks like frb (being really a visualization tool) uses a ngp scheme and doesn't interpolate. Is that true? That being so, would smoothed_covering_grid do what I want? (i.e. give me an interpolated field between two positions where none of the values are the same for different positions)? Is it called via: scg = pf.h.smoothed_covering_grid(4, na.array([0.,0.,0.]), na.array([32.,32.,32.])) Then, I can just grab the appropriate slice of cells? Does it return the 3D data as a 3D array or 1D? i.e. can I do: scg["Accel3Name"][0,0,0] If not, is it obvious to work out which the centre slice of cells are? Or can I use "slice" and specify the scg as the object? Elizabeth

problem with fields that use ghost zones
by Britton Smith 30 May '12

30 May '12

Hi everyone, I'm having a problem using fields that use ghost zones. The following simple script: http://paste.yt-project.org/show/2010/ gives this error: http://paste.yt-project.org/show/bOikDPScBBtDiUGvH11X/ I am working from the tip, but I get the same behavior from yt/2.3. In yt/2.2, everything is working. I am working now to narrow that range down a bit, but does anyone have an idea? Britton

Hi, Recently I changed my OS from ubuntu to Kubuntu 12.04 LTS so I re-installed yt, and the old readline problem comes up again: While I'm in the script environment of python that comes with yt, the readline service is not available.(That's why I pulled out this old message). I followed all the suggestions from this email which helped me solved this problem previously, but it doesn't work this time: First I followed Elizabeth and Casey's suggestion tried to pip install readline, but it keeps saying "libncurses.a: could not read symbols: Bad value" and then "error: gcc fails and exit with status 1". After searching for a quite a while without any luck on web, I tried to build readline directly in ~/yt-x86_64/lib/python2.7/site-packages, guessing that might work. But it turned out still not working. Can anyone help me out with this?
