Detailed Description

Class for a magnetized (tabulated) equation of state.

()

This EOS depends on two variables $(n, B)$: density (or log-enthalpy) and the magnetic field amplitude. The interpolation through the tables is a cubic Hermite interpolation, which is thermodynamically consistent, i.e. preserves the Gibbs-Duhem relation.
