central_density.hpp File Reference

Prescribe central density through the continuous enthalpy: h(0) - h_EOS(rho_c) = 0. Generally this is not needed; however, in the particular case of an n=3 polytrope with no rotation the central density becomes ill-defined and must be prescribed to avoid a singularity in the solution. More...
