eos_had_tabulated
: public o2scl::eos_had_eden_base¶ Zero-temperature EOS from a table.
This assumes a symmetry energy which depends quadratically on the isospin asymmetry in order to construct an EOS from a table of baryon density and energy per baryon for both nuclear and pure neutron matter.
Note: If using a tabulated EOS to compute derivatives (like the compressibility which effectively requires a second derivative), it is important to tabulated the EOS precisely enough to ensure that the derivatives are accurate. In the case of ensuring that the compressibility at saturation density is reproduced to within 3 significant figures, the EOS should be specified with at least 6 digits of precision on a grid at least as small as 0.002 \( \mathrm{fm}^{-3} \).
- Idea for Future:
Storage in a o2scl::table object isn’t necessary, and storing in a vector object is more efficient.
- Idea for Future:
Allow the pressure to be specified to make the EOS more accurate?
