CMB not working with enzo

[dnarayanan]

right now the code block in enzo_tributary:

   energy_density_absorbed=energy_density_absorbed_by_CMB(
   energy_density_absorbed = np.repeat(energy_density_absorbed.value,amr['density'].shape)


    d = SphericalDust(cfg.par.dustdir+cfg.par.dustfile)
    if cfg.par.SUBLIMATION == True:
        d.set_sublimation_temperature('fast',temperature=cfg.par.SUBLIMATION_TEMPERATURE)
    m.add_density_grid(amr['density'],d),specific_energy=energy_density_absorbed)
    m.set_specific_energy_type('additional')
 #m.add_density_grid(amr['density'], cfg.par.dustdir+cfg.par.dustfile)

doesn't work due to the inlcusion of the specific_energy
