New issue 619: user-defined outputs with Athena https://bitbucket.org/yt_analysis/yt/issue/619/user-defined-outputs-with-at… Anonymous: Dear Developers, I would like to visualize/analyze some streaming-nstability simulation outputs created with Athena with yt. The output is a user-defined variable, such as the particle density enhancement. The (2-d) data is written to a .vtk file which I tried to read with yt using the load command. I Immediately get errors. Here is the session information:… [View More] pf = load("id0/Streaming2d.0000.difdpar.vtk") yt : [INFO ] 2013-08-05 15:30:17,851 Temporarily setting domain_right_edge = -domain_left_edge.

Issue #618: Install script fails when compiling with gcc provided by MESA sdk (yt_analysis/yt)
by Nathan Goldbaum Aug. 5, 2013

Aug. 5, 2013

New issue 618: Install script fails when compiling with gcc provided by MESA sdk https://bitbucket.org/yt_analysis/yt/issue/618/install-script-fails-when-co… Nathan Goldbaum: It seems a lot of people have the gcc provided by the [MESA](http://mesa.sourceforge.net/) sdk in their `$PATH`. The install script currently fails while trying to compile mysql using this compiler. I've only seen this on a mac, and while building yt with xcode's gcc still works, it's a bit confusing for new users who … [View More]

Issue #616: Loading vtk files from Athena joined with their join_vtk.c executable (yt_analysis/yt)

New issue 616: Loading vtk files from Athena joined with their join_vtk.c executable https://bitbucket.org/yt_analysis/yt/issue/616/loading-vtk-files-from-athen… Anonymous: It seems that when loading Athena vtk files, if the file was created by the Athena supplied executable join_vtk (for stitching together vtk files created from the different processors in an mpi run) then the loaded data is missing all the fields except the 'density' field.

Hi all, Just a heads up, I will be away until the 15th or so. Don't feel that PRs need to wait for me to return unless they are something that definitely needs my attention. Matt

New issue 614: yt's libraries are not compatible with CentOS binaries https://bitbucket.org/yt_analysis/yt/issue/614/yts-libraries-are-not-compat… Nathan Goldbaum: I was trying to use `eog` to look at some images on a supercomputer. Under the yt environment, I get a seg fault when I try to use `eog`, but after deactivating and trying again, everything works correctly. `eog` is dynamically loading yt's freetype and libz. I've pasted a shell session with information about this issue below: … [View More]
