Air as an ideal gas with LS-DYNA ICFD

Does anybody here know how to enable the energy equation that would normally be used for conjugate heat transfer problems and also for problems where you are using air as an ideal gas?

(I read the ICFD theory manual by Inaki and it doesn't say in there how to do that.)

The CE/SE method which normally enables you to perform compressible flow simulations doesn't give you the option for selecting the turbulence/viscosity model that's available with the ICFD solver.

Thanks.
