[yt-users] Pressure in Enzo methods

[David Collins]

Hi, Matt--

Thanks for your input.  In frontends/enzo/feilds.py, I see where the
thermal_energy is computed based on HydroMethod=4,6, but there's no
pressure field.  Which in principle is fine, since the computation in
yt/fields/fluid_fields.py (in setup_fluid_fields) is fine.  Does that
instance not get called?
