Hi Kaitlin, Are you using the main development version or Sam's Athena-specific branch? I think we're using different yt code, since we're getting different output. I'm using the main development branch. In that branch, if domain_right_edge doesn't equal -domain_left_edge, you have to set it explicitly. When I just load the file, I get this: In [4]: pf = load("cyl_disk.0000.vtk") yt : [INFO ] 2012-11-15 21:28:49,259 Please set 'domain_right_edge' in parameters dictionary argument if it is not equal to -domain_left_edge. yt : [INFO ] 2012-11-15 21:28:49,260 Parameters: current_time = 0.0 yt : [INFO ] 2012-11-15 21:28:49,260 Parameters: domain_dimensions = [ -36.57142857 127.99998696 nan] yt : [INFO ] 2012-11-15 21:28:49,261 Parameters: domain_left_edge = [ 1. -1.570796 0. ] yt : [INFO ] 2012-11-15 21:28:49,261 Parameters: domain_right_edge = [-1. 1.570796 -0. ] yt : [INFO ] 2012-11-15 21:28:49,262 Parameters: cosmological_simulation = 0.0 As you can see, the INFO that I get about the domain edges is different from yours. When I set domain_right_edge explicitly, I get this: In [5]: pf = load("cyl_disk.0000.vtk", parameters={'domain_right_edge':[15.,np.pi/2.,1.0]}) yt : [INFO ] 2012-11-15 21:25:27,282 Parameters: current_time = 0.0 yt : [INFO ] 2012-11-15 21:25:27,283 Parameters: domain_dimensions = [ 256. 128.00000028 inf] yt : [INFO ] 2012-11-15 21:25:27,283 Parameters: domain_left_edge = [ 1. -1.570796 0. ] yt : [INFO ] 2012-11-15 21:25:27,291 Parameters: domain_right_edge = [ 15. 1.57079633 1. ] yt : [INFO ] 2012-11-15 21:25:27,291 Parameters: cosmological_simulation = 0.0 So the "inf" in the last domain dimension isn't right, but at least it has the r and z dimensions correct. I suspect that what has happened is that you might be using a revision of Sam's Athena-specific yt branch which probably does not have 2D support built in, since that was put in just a few days ago. If you use the main development branch and update to the latest revision, you should get the same result that I did above. I have a feeling I know how to fix the "inf" in the last dimension, but I should probably try Sam's updates that he mentioned and seeing what happens then.

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
