Since version 2026, Flux 3D and Flux PEEC are no longer available.
Please use SimLab to create a new 3D project or to import an existing Flux 3D project.
Please use SimLab to create a new PEEC project (not possible to import an existing Flux PEEC project).
/!\ Documentation updates are in progress – some mentions of 3D may still appear.

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 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) | B(Stress) | D(E) | k(T) | ρCP(T) | |
| Magneto Static | yes | yes (2D) | ||||
| Transient Magnetic | yes | yes | yes (2D) | |||
| Steady State AC Magnetic | yes | yes | ||||

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.
