Altair Flux™

Accelerate Motor, Sensor, and Actuator Design


High performance geometric description

  • Embedded sketcher and modeler with fully parametrized modeling constructs

  • Advanced CAD import & export

  • Defeaturing & simplification capabilities

  • A dedicated environment for electric rotating machines design in 2D&3D

  • Skew modeling capabilities avoiding long 3D analysis thanks to 2,5D models.

An easy and flexible mesh generator

Flux provides different meshing technologies that can be mixed in both 2D and 3D situations to help the user to quickly get a precise mesh:

  • Smart automatic mesh and fine manual control of mesh size and distribution

  • Linked mesh between identical geometric entities

  • Auto-adaptive mesh refinement during solving in 2D & 3D.

Advanced physical properties for high performance calculations

A full range of physical models to simulate the low frequency behavior of electromagnetic devices.

  • Magnetic: Static, steady state AC magnetic, transient

  • Electric: Electrostatic, conduction, steady-state AC electric

  • Thermal: Steady state AC thermal, transient

  • Thermal couplings: Electro-thermal, magneto-thermal

  • Embedded electric circuits and rigid body motion capabilities

Advanced modeling techniques for accurate and fast results

  • Non-meshed coils

  • Thin regions represented by surface models (no need to mesh the thickness)

  • Non-linear anisotropic material behavior, hysteresis modeling

  • Skin and proximity losses in windings

  • Partial Element Electrical Circuit (P.E.E.C.) method for conductor modeling

Solving process: A fast and robust solver

Fully parametric solver allowing geometrical or physical parameter sweeps

  • Several iterative or direct linear solvers

  • Parallel computing using multithreading and distributed memory multiprocessors

  • Robust non-linear solvers.

  • Distributed parametric studies across several cores or machines.

Results post-processing: Show your results and convince

Flux provides a complete and versatile postprocessor enabling the analysis of results from multi-parametric solving. It gives access to various quantities such as:

  • Potential, flux density, temperature, electric and magnetic fields

  • Global quantities: magnetic flux, inductances, stored energy

  • Iron losses, Joule losses in conductors, skin effect visualization

  • Quantities on electrical components: current, voltage, power, inductance

  • Extraction of RLC values of conductors and export of equivalent circuits

  • Mechanical quantities: position, velocity, force, torque, speed

Software Interoperability

Because Flux is used in global design workflows, it can be easily connected to other software, being for multiphysics analysis, optimization or system-level simulation. Flux is able to import meshes from SimLab or HyperMesh, allowing to deal with complex 3D CAD input files in an efficient way. The connection to PBS will let you take advantage of the full power of remote HPC clusters.
