- Physical applications
  Flux allows to model different physical phenomena, and includes various applications (magnetic, electrical, thermal and thermal coupled).
- Circuit and Kinematic Couplings
  Flux is coupled to a circuit context allowing to model the sources of the devices.Flux also allow to model the movement via a kinematic coupling.
- Co-simulation between Flux and another software
  Flux is able to couple with several softwares allowing to model mutliphysics phenomena.
- Dedicated couplings
  Several dedicated couplings are implemented in Flux to, carry out vibro-acoustic studies, magneto-thermal studies and more.
- 3D Overlay
  Flux has predefined models for rotating machines via Overlays allowing to describe a geometry, a mesh and a physics adapted to the wished machine.
- Flux API
Flux Skew
Flux Skew is a module allowing to facilitate the realization of a quasi 3D or 2 ½ D study starting from a 2D description.
Flux PEEC
Flux PEEC is a 3D modeling module dedicated to electrical interconnections of power electronics devices. It also provides RLC extraction and generation of SPICE-like equivalent circuits.
Material Identification
Flux provides a unified Material Identification tool based on the Altair Compose environment allowing to run an identification of the coefficients required to create material in Flux.
Material Manager
Flux has a material manager with its own material base.The user can create his own material base and import them into the Flux models to be studied.
Flux e-Machine Toolbox
FeMt is a application in Flux dedicated for Electric Machine which permits to compute and postprocess results like efficiency maps.
Flux Examples
See the lists of examples 2D, 3D, SKEW and PEEC with all available documents and all project and python files.
Flux in SimLab Examples
