Material: about

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 dielectric property D(E)
  • their thermal conductivity k(T)
  • their specific heat ρCP(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) D(E) k(T) ρCP(T)
           
Magneto Static yes        
Transient Magnetic yes yes      
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)   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.
