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.

The second line in the file should contain a name given by the user to the EOS. The following lines should contain the EOS parameters (one parameter per line), in the same order than in the class declaration.
