Detailed Description

FI (fully-ionised, constant-gamma) EoS kernels for the eos% family.

Carved out of mod_eos.t (the per-type split). The fully-ionised ideal gas: p = (gamma-1) eint, constant Gamma_1 = gamma, temperature T = p/(R rho) with R the constant ionisation R-factor. update_eos is a no-op (nothing cached). mod_eos re-exports the public names so existing use mod_eos callers are unaffected; eos_finalise wires these as the FI pointer targets.

Function/Subroutine Documentation

eos_finalise_fi()

subroutine, public mod_eos_fi::eos_finalise_fi

FI arm of eos_finalise: wire the ideal-gas getter set and the fully-ionised particle counts (2 + 3*A_He per H; ne/nH = 1 + 2*A_He). No tables to load.

nothing cached for ideal gas

eos_init_fi()

subroutine, public mod_eos_fi::eos_init_fi

get_Te_FI is PRIVATE: bound to eosget_Te inside eos_finalise_FI only. The rest stay public: update_eos_FI (ffhd_phys), get_gamma1_FI (the seam phys_get_gamma1), get_temperature_from_{eint,pressure}_FI (reused by mod_eos_PI), and the init/finalise dispatcher arms.

FI arm of eos_init (before units are known): wire the FI temperature-from-pressure getter, which must be live before (m)hd_link_eos captures it into the radiation fluid object.

Parameters

[in]	ixi	Assumes input energy is internal energy
