Thank You very much... On Tue, Jul 9, 2013 at 10:40 AM, Andrew Myers wrote:

Hi Reju,

The Enzo-specific fields, including TotalEnergy and GasEnergy, are defined in yt-hg/yt/frontends/enzo/fields.py. There is also yt-hg/yt/data_objects/universal_fields.py, which contains some field definitions (like 'CellMass') common to all the frontends.

Dear all,

In yt distribution where I can find the definition of Enzo Fields that YT knows (like TotalEnergy, GasEnergy, etc. ).

Please help me.

As a late addition to these responses, I would also add that there is a full listing of the defined fields in the online documentation. The fields are listed for the general yt code as well as for each simulation-code-specific field: http://yt-project.org/doc/field_list.html Cameron On Tue, Jul 9, 2013 at 1:19 AM, Nathan Goldbaum wrote:

Hi Reju,

Well, that depends on your dataset, since enzo will not necessarily write the same fields to disk for every simulation. Suppose you've loaded a dataset like so:

...

...

...

pf = load('DD0050/DD0050') pf.h

then pf.h.field_list will be the list of the fields that are in the dataset on disk and pf.h.derived_field_list will be the list of derived fields that are available based on pf.field_list (i.e. the list of fields enzo originally wrote to disk). These are just regular python lists, so you can count them, sort them, and iterate over them:

...

...

...

len(pf.h.field_list) sorted(pf.h.field_list) for f in pf.h.field_list: print f

You might also find pf.field_info useful. This object is a mapping from field names to FieldInfo objects that contain information about fields. For example, if I wanted to know more about the RadialVelocity field, I could do:

...

...

...

print pf.field_info['RadialVelocity'].get_source()

This prints out the python source code for the field. You can also just look in universal_fields.py for the same information, although sometimes it's nice to see the source for a derived field from inside a running python session.
