int
set_base_eos
(eos_had_sym4_base &seb)¶ Set the base equation of state.
-
int
test_eos
(fermion &ne, fermion &pr, thermo <h)¶ Test the equation of state.
This compares the chemical potentials from calc_e_sep() to their finite-difference approximations in order to ensure that the separation into potential and kinetic parts is done properly.

int
calc_e
(fermion &ne, fermion &pr, thermo <h)¶ Equation of state as a function of density.
