    • 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

    • How to Configure the Memory in Flux?

  • Flux Skew

    Flux Skew is a module dedicated to the analysis of rotating electric machines with skewing, allowing a straightforward geometric and physical description in 2D and the consideration of continuous or step skewing effects.

  • 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

    The Material Identification tool is based on the Altair Compose environment and allows determining from measurements the parameters and coefficients required to create a material in Flux.

  • Altair Material Datacenter (AMDC)

    AMDC is a comprehensive material database maintained by Altair and partner suppliers of engineering materials. Ready-to-use, Flux-compatible models may be obtained directly from this database for a growing number of materials.

  • 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.
