Re: [yt-users] Question about visualization of the derived Fields

Thank you David and Matthew, I have looked the yt webpage about derived Field. But, I can not find where in the script the definition goes. For example I wrote the script to make slice as follow ------------------------------------------------ from yt.mods import * from yt.analysis_modules.api import EnzoSimulation import matplotlib.pylab as pylab def _Temperature(field, data): DEFAULT_MU = 0.6 return data["Gas_Energy"]*(data.pf[Gamma]-1)*DEFAULT_MU add_field("Temperature", function=_Temperature) es = EnzoSimulation("RotatingSphere.enzo", initial_time=0.0, final_time=50.) time = [] i = 0 for output in es.allOutputs: # load up a dataset pf = load(output['filename']) # calculate the time of output time.append(0.1*i) i = i + 1 # create density slices pc = PlotCollection(pf, center=[0.5,0.5,0.5]) pc.add_slice("Temperature", 0) pc.add_slice("Temperature", 2) pc.save("t%05.2f" % time[i-1]) -------------------------------------------------------------------- But this python script crashed. How and where can I define new field in the script? Thank you Junhwan Matthew Turk wrote:

Hi YT uses,

I would like to know how make slice, projection, or volume rendering plots for derived Fields. For example, my enzo simulation output only has gas_energy (no temperature field in grid data) and I would like to make temperature map with add_slice, simply write add_slice("Temperature", 0) causes an error. Is there any way this visualization can be done with derived Field?

Thank you, Junhwan
