Quick Guide. Technical information and caveats. More information available on mouseover.

Data type:
Temperature (K) Pressure (GPa)

Phase transition:If the phase has a phase transition between ambient pressure and the first data point. These options have no effect for temperature data and can be left blank.
Use a critical pressure?:
Critical pressure:

Advanced Options:
Finite strains are more appropriate for large strains. The derivation of the Birch-Murnaghan EoS uses finite Eulerian strain.
Finite strain?
Eulerian strain?

Data:One phase only
T or PK or GPaσ(T or P)K or GPaabcαβγ
