Advantages of our software for the design of electric actuators


  • Strong Electromechanical coupling in 2D and 3D to account for the motion (translation, rotation, free position, constant or variable speed) during the FEM computation 
  • Strong Circuit and FEM coupling with electric circuit descriptor integrated in Flux 
  • Rapid and accurate solvers
  • Easy multi-parametric studies


  • Versatile and intuitive, 
  • Complete library of electro-mechanical components,
  • VHDL-AMS language

Flux-Portunus cosimulation:

  • Allows using important library of model of electronics component (diode, transistor, etc…)
  • Allows integrating the actuator on a whole mechatronic chain

  • Allows taking into account of eddy current

Flux-Simulink® cosimulation


  • Automated coupling GOT-It / Flux 
  • Optimization of FEM boosted thanks to strategies based on design of experiments approach (Screening and Indirect optimization with response surfaces) 

  • Different levels of use
