Scalar Eos::press_ent ( const Scalar ent,
int  nzet,
int  l_min = 0,
const Param par = 0x0 
) const [inherited]

Computes the pressure from the log-enthalpy and extra parameters.

Parameters:
ent [input, unit: $c^2$] log-enthalpy H defined by $H = c^2 \ln\left( {e+p \over m_B c^2 n} \right) $, where e is the (total) energy density, p the pressure, n the baryon density, and $m_B$ the baryon mass
nzet number of domains where the pressure is to be computed.
l_min index of the innermost domain is which the pressure is to be computed [default value: 0]; the pressure is computed only in domains whose indices are in [l_min,l_min+nzet-1] . In the other domains, it is set to zero.
par possible extra parameters of the EOS
Returns:
pressure [unit: $\rho_{\rm nuc} c^2$], where $\rho_{\rm nuc} := 1.66\ 10^{17} \ {\rm kg/m}^3$
