2d radial profiles
by david collins April 17, 2010

April 17, 2010

Hi, all-- Is it possible to make a 2d radial profile from a projection with the existing profile tool? I think a better question is how do I make an extraction from a projection that I can then hand to BinnedProfile1d? Thanks, d. -- Sent from my Stone Tablet and carried by my Pterodactyl.

If statement for particles existing?
by Elizabeth Harper-Clark April 16, 2010

April 16, 2010

Hi guys, I sometimes have particles in my sims and when i do I want to plot them. At the moment I have: if sp["ParticleMassMsun"].size > 0: p.modify["particles"](1.0, p_size=10.0, col='k') but if there are no particles I get this error message: yt INFO 2010-04-16 11:58:29,408 Getting ParticleMassMsun using ParticleIO Traceback (most recent call last): File "Density_movie.py", line 29, in <module> if sp["ParticleMassMsun"].size > 0: File "/… [View More]

solution to wxPython installation problem
by Michael Kuhlen April 15, 2010

April 15, 2010

I just installed yt 1.6 (stable branch) for the first time. I ran into some trouble with the wxPython installation. I realize that it's an optional component, but since I found a solution to my problem, I thought I'd share it here. I'm installing yt on an x86_64 machine running Ubuntu 9.04, 2.6.28-18. The error I got during the wxPython installation was: src/gtk/_gdi_wrap.cpp:31407: error: ‘class wxGraphicsRenderer’ has no member named ‘CreateBitmap’ Some googling revealed this: http://… [View More]

projection depth
by Luigi Iapichino April 13, 2010

April 13, 2010

Dear all, by comparing volume renderings and projections in my simulation I realised that I don't have control on the projection depth, in the latter case. This is the relevant part of my script: ... L = 0.1 # projection width pf = load(data_dir+fn) # load data reg = pf.h.region([0.5, 0.5, 0.5],[0.45,0.45,0.45],[0.55,0.55,0.55]) # a small region #reg = pf.h.region([0.5, 0.5, 0.5],[0,0,0],[1,1,1]) # the whole box pc = PlotCollection(reg, center=[0.5,0.5,0.5]) p = pc.add_projection("… [View More]

Dear all, I get the following error when trying to plot a radial profile of the density. Does anyone have an idea how to solve this ?

problems loading yt
by Brian O'Shea April 6, 2010

April 6, 2010

Dear yt-users, I'm having a very peculiar problem, and I wonder if any of you have experienced this. I have been using my desktop machine to make tons of images of some enzo simulations - literally several thousand images at this point - and yt has mysteriously stopped working. I haven't done anything to python, attempted to upgrade yt, or anything like that... It just started throwing errors about 800 images into a script. It seems that I can get this error by simply typing 'python' and … [View More]
