Detailed Description
template<bool IsRelativistic>
class EquationsOfState::PolytropicFluid< IsRelativistic >
Equation of state for a polytropic fluid.
A polytropic equation of state \(p=K\rho^{\Gamma}\) where \(K\) is the polytropic constant and \(\Gamma\) is the polytropic exponent. The polytropic exponent is related to the polytropic index \(N_p\) by \(N_p=1/(\Gamma-1)\).

Initial value:
= {
"A polytropic fluid equation of state.\n"
"The pressure is related to the rest mass density by p = K rho ^ Gamma, "
"where p is the pressure, rho is the rest mass density, K is the "
"polytropic constant, and Gamma is the polytropic exponent. The "
"polytropic index N is defined as Gamma = 1 + 1 / N."}
