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).
