Equations of state

For more accuracy, it may be necessary in some cases to better define the electromagnetic properties of some materials. Several equations of state are provided by the solver :

  • A Burgess model giving the electrical conductivity as a function of temperature and density. The Burgess model gives the electrical resistivity vs temperature and density for the solid phase, liquid phase and vapor phase. For the moment, only the solid and liquid phases are implemented.

  • A Meadon model giving the electrical conductivity as a function of temperature and density. The Meadon model is a simplified Burgess model with the solid phase equations only.

  • A tabulated model allowing the user to enter his own load curve defining the conductivity function of the temperature.

  • A tabulated model allowing the user to enter his own load curve defining the magnetic flux density function of the magnetic flux intensity (or vice versa).
