New issue 1301: Dimensions for energy fields are confusing https://bitbucket.org/yt_analysis/yt/issues/1301/dimensions-for-energy-field...
The dimensions for `("gas", "thermal_energy")` are of specific energy, energy per unit mass.
The dimensions for `("gas", "kinetic_energy")` are of energy per unit volume.
Different hydro codes adopt different dimension conventions for total energy and thermal energy. It seems that we need a consistent naming scheme for these that is unambiguous, e.g. perhaps `("gas", "kinetic_energy_density")`?
