[yt-users] multiply a function of a field with another field

[Matthew Turk]

Hi Reju,

Your best bet would be to do this with a derived field; there are some
examples in the docs.  But, as a simple example, this would accomplish
it:

--
from yt.mods import *

@derived_field(name = "MyField")
def my_new_field(field, data):
    return data["Density"] * data["Temperature"]
--

In the docs it mostly uses the function "add_field" rather than
@derived_field, but the result is the same.  This returns Temperature
* Density.  You can then plot "MyField" or ask for it or whatever, and
it will be the result.

Hope that helps!
