Hi--

So also use yt in a non-cosmological-enzo manner, and override the units in all sorts of ways, including "just take it from the file". I think that this is what you're looking for. What I do is subclass the EnzoStaticOutput object, and have the derived class send conversion_override and parameter_override keywords to to the EnzoStaticOutput constructor. You'll probably need to subclass the OrionStaticOutput or sompin.

At the bottom of this email is an OutputType subclass that takes the fields directly out of the file and (effectively) does no unit conversion. I just do

pf = FileStaticOutput(path)

as normal (not sure how/if this works with 'load'). I also use this to do analysis with units that aren't automatically gotten (non-cosmological sims in my version of Enzo have no units info output, so I do it by hand.) by setting 'Density':(whatever I need to multiply the data in the code by to get it into cgs), etc, in the arguments.

I haven't bothered with getting the labels on plots to be correct-- I think you do this through through lagos.fieldInfo[field]._projected_units and lagos.fieldInfo[field]._units.

Let me know if anything doesn't work properly.

import yt.lagos.OutputTypes as OT

class FileStaticOutput(OT.EnzoStaticOutput): def __init__(self,args,**kwargs): OT.EnzoStaticOutput.__init__(self,args,conversion_override={'Density': 1,

'x-velocity': 1,

'z-velocity': 1,

'y-velocity': 1,

'Total_Energy': 1},

parameter_override={'LengthUnits': 1,'LengthUnit': 1, 'Time': 1}, **kwargs)
