Materials

Materials can be:

created directly in the Flux project
imported from a materials database*

* Information concerning the materials database (database location and managing of materials in database) is presented in chapter Material Manager.

Properties of materials and physical application

Materials possess various physical properties.

They can be characterized by:

their magnetic property B(H) and/or B(H,T)
their electric property J(E) and/or J(E,T)
their magneto-mechanical property B(Stress)
their dielectric property D(E)
their thermal conductivity k(T)
their specific heat ρC_P(T)

Physical properties, useful for modeling, depend on the current (active) physical application. The table below summarizes the “dependencies” between physical properties of materials and physical application.

Physical application	Physical property
	B(H)	J(E)	B(Stress)	D(E)	k(T)	ρC_P(T)

Magneto Static	yes		yes (2D)
Transient Magnetic	yes	yes	yes (2D)
Steady State AC Magnetic	yes	yes

Electro Static				yes
Electric Conduction		yes
Steady State AC Electric		yes		yes

Steady Thermal					yes
Transient Thermal					yes	yes

Steady State AC Magnetic coupled with Transient Thermal	yes	yes			yes	yes
Electric Conduction coupled with Transient Thermal (2D)		yes			yes	yes
Steady State AC Electric coupled with Transient Thermal (2D) - available in Advanced mode only		yes		yes	yes	yes

Note: The existence of a property B(H) is compulsory to use the material in a magnetic application, but it is useless for an electric or thermal application. It is the same for the five other properties.

Models

Models provided for physical properties are presented in chapter Materials: principles.

Correspondence of the models

The models, provided with the Material manager, and the models, provided in Flux, are all compatible.

The correspondence between the names of Material manager models and the names of Flux models is presented in List of models for each properties.
