FARGO Adiabatic writes by default the gas surface density, radial and azimuthal velocity and temperature (and not the thermal energy). You can specificy to write the gas thermal energy, velocity divergence, as well as the heating source term of the energy equation. All you need is adding in your parameter file: WriteEnergy Yes if for instance you wish to write the gas thermal energy (note that it is case insensitive). The other booleans, declared in var.c, are WriteDivv and WriteQplus.
