Hi John, I've put the inputs file and the first output file in vtk and binary format at: http://jila.colorado.edu/~kakr3691/Athena/ I'm using the development branch (though not necessarily up to date). One thing Matt and I discussed was that using the athena binary data might ultimately be better than the vtk files. My uneducated guess is that the binary data would read in like the 2D cartesian, much like Flash. -Kaitlin On Nov 15, 2012, at 3:49 PM, John ZuHone <jzuhone@gmail.com> wrote:
Hi Kaitlin,
At the moment yt supports 2D and 3D cartesian data for Athena (the former only very recently in the yt development tree).
True cylindrical coordinate support (for all codes) is planned for yt 3.0. FLASH 2D cylindrical reads in fine, but this is mostly by accident since the data format in the file is the same as 2D cartesian. I'm guessing this means that the Athena vtk files for cylindrical coordinates are set up slightly differently from the cartesian coordinates.
Are you using the stable or development version of yt? We might be able to get something working along the same lines as FLASH if you have a file you wouldn't mind providing, as a stepping-stone to true support for cylindrical coordinates.
Best,
John

Hi,
I gather that cylindrical geometries aren't supported. Is it possible to force yt to read in cylindrical coordinates as though they were cartesian?
When I try to load an athena vtk in cylindrical, I get:
In [32]: pf = load("cyl_disk.0001.vtk") yt : [INFO ] 2012-11-15 15:31:26,443 Temporarily setting domain_right_edge = -domain_left_edge. This will be corrected automatically if it is not the case. yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: current_time = 0.001080635 yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: domain_dimensions = [ -37 128 -2147483648] yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: domain_left_edge = [ 1. -1.570796 0. ] yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: domain_right_edge = [-1. 1.570796 -0. ] yt : [INFO ] 2012-11-15 15:31:26,445 Parameters: cosmological_simulation = 0.0
This is a 256 by 128 grid, and the dimensions should be -pi/2, pi/2 and 1, 15.
Thanks, Kaitlin
