Hi yt-users,
I am trying to make phase_objects of Athena data. I am able to make phase_objects if I use the "expected" set of variables (will show below), but kill my kernel or am kicked out of python if I try and use an "unknown field" read in from a set of vtk files.
from yt.mods import *
pf = load("id0/rps.0080.vtk")
yt : [INFO ] 2012-12-13 23:27:08,678 Temporarily setting domain_right_edge = -domain_left_edge. This will be corrected automatically if it is not the case.
yt : [INFO ] 2012-12-13 23:27:08,974 Parameters: current_time = 40.00096
yt : [INFO ] 2012-12-13 23:27:08,974 Parameters: domain_dimensions = [1048 1048 655]
yt : [INFO ] 2012-12-13 23:27:08,975 Parameters: domain_left_edge = [-3.2 -3.2 -2. ]
yt : [INFO ] 2012-12-13 23:27:08,976 Parameters: domain_right_edge = [ 3.2 3.2 2. ]
yt : [INFO ] 2012-12-13 23:27:08,977 Parameters: cosmological_simulation = 0.0
yt : [INFO ] 2012-12-13 23:27:13,214 Adding unknown field specific_scalar[0] to list of fields
pf.h.field_list
['density',
'pressure',
'velocity_z',
'velocity_x',
'velocity_y',
'specific_scalar[0]']
alld = pf.h.all_data()
tracerp25 = alld.cut_region(["grid['specific_scalar[0]'] > 0.25", "grid['z'] > 0.01"])
##These commands works:
radmean = tracerp25.quantities["WeightedAverageQuantity"]("Radius","Ones")
pc = PlotCollectionInteractive(pf)
pc.add_phase_object(alld,["z","velocity_z","CellMass"],weight=None)
#The calls below fail. There is no error message. If I am in iPython,
#the kernel dies. If I am running on a computer, it freezes and
#eventually I just get the message
#Killed
pc.add_phase_object(alld,["z","specific_scalar[0]","CellMass"],weight=None)
pc.add_phase_object(tracerp25,["z","velocity_z","CellMass"],weight=None)
#If I read in a single vtk file ("id122/rps-id122.0080.vtk") the above
#commands workAny help would be much appreciated! Thanks,
