Dear all, Thank you for your help in advance. I am currently running cosmological simulations using Nyx code. And while trying to over plotting particles on the density slice, I encountered the following error which I couldn't resolve. I will greatly appreciate your help. Traceback (most recent call last): File "./OverPlotingParticles.py", line 14, in <module> pc.set_width(1.0, '1') # change width of our plot to the full domain File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/… [View More]

YTSphereTooSmall
by Geoffrey So May 23, 2012

May 23, 2012

I get this behavior when I was trying to compare the sphere stuff with my ellipsoid mod, I sometimes get spheres that are bigger than the cell yet raise the exception YTSphereTooSmall. In my script I print out the sphere's radius, virial radius (halo.maximum_radius(), halo.virial_radius()) and halo number (halo.id), and prints out a smaller than cell warning and return 0 for all attributes when it raises the YTSphereTooSmall exception: halo 5 radius 1.5050650880000000e-02 virial radius 1.… [View More]

Hi guys, After a projection and a FixedResolutionBuffer like this: proj = pf.h.proj(axis, "Temperature", None)frb1 = FixedResolutionBuffer(proj, (xmin,xmax,ymin,ymax), res)write_image(na.log10(frb1["Temperature"]), "output.png") I see an inverted image (my computational box is half a cube, z>0 only):http://i.imgur.com/AqWKD.png Is the problem in write_image? Or inside the projection/FRB?How to fix this (without transpose)? Thanks, Max

I was wondering if there's anything I need to worry about? -------------------------------------------------------------------------- An MPI process has executed an operation involving a call to the "fork()" system call to create a child process. Open MPI is currently operating in a condition that could … [View More]
