Together with a highly qualified support network and a strong community of users, Altair and its Flux team provide recognized expertise in electrical engineering.

In a greener and more electric world, engineers can rely on Flux to assist in designing energy efficient devices, bringing more innovation and value to your customers.
Flux, using breakthrough technologies, is the right tool for the analysis, design and optimization of modern applications. Featuring embedded multi-parametric analysis capabilities, its open interface deals with different simulation domains and is well suited for multiphysics couplings.

Benefits:

Open and intuitive, Flux can be easily included in your design workflow to deliver reliable analysis results. With the most advanced numerical methods available, it deals with complex modeling situations.

Its multi-parametric capabilities allow an efficient search of the design space for optimal performance of your device. Customization, automation and connection to CAD tools are available for maximum productivity.

Accurate
Through the years, Flux has proven its ability to get close to measurements and to reproduce with great accuracy complex phenomena. Flux generates results engineers can trust allowing them to concentrate on innovation. Flux solvers are constantly being improved to bring the best solving speed, allowing for the evaluation of thousands of design configurations.

Flexible
Because each simulation is unique, Flux can be easily adapted to specific needs. Different options are available to fine tune the models and the solvers, bringing accurate results in the most efficient way. With its embedded scripting tools and the ability to write macros, Flux captures simulation processes and automates them, thus speeding-up the everyday use of the software.

Parametric simulation
Using a parameter to define a geometric dimension or a physical characteristic is one of the Flux fundamentals. Linking several parameters together through equations is also very easy, and users can intuitively explore the influence of any parameter.

Flux also takes advantage of the distribution of the calculations, allowing for the evaluation of numerous design configurations with an optimized computational time.

Interoperable
The connection to the Altair suite enables users to work in a global creative environment. Flux can be coupled to the best available 3D analysis software to consider multiphysics and get the most realistic representation of phenomena, or to system level simulation tools to design control strategy.

New Features:
Accelerate your design when dealing with 3D complex CAD geometries
A number of new tools were introduced in Flux™ 12.3, which enabled the import of 3D meshes directly from HyperMesh® and SimLab®, bringing new capabilities for CAD geometry simplification and meshing. Flux 2018 improves the existing workflow, bringing more flexibility as well as making it applicable to any type of application.

The following functionality is available: change the order of the mesh elements, build an infinite box after import, account for movement, deal with any type of coil description or importing a surface mesh.

Solving faster in 3D using new HPC capabilities
Improvements introduced in Flux 2018 focus on large 3D models with eddy currents.
New mathematical formulations are now available to help the non-linear convergence in such cases, particularly in the frequency domain.
The linear solver has also been updated with the latest version of MUMPS, and the possibility to use it in a distributed memory mode, allowing Flux to run on clusters with larger numbers of cores. This brings great accelerations for 3D models with large meshes.
It is now also easier to benefit from the computing power of remote clusters thanks to the connection of Flux with PBS Works™, Altair’s industry-leading workload manager and job scheduler for high-performance computing.

Going further in the coupling with mechanical simulation
The coupling with OptiStruct ® for mechanical design has been updated with the new version. For vibration analysis of electric machines, the post-processing capabilities of Flux have been extended with more options in the data visualization and export.

For static stress analysis, it is also now possible to export force densities from a magnetostatic model or from a step of a transient magnetic computation to a structural simulation. Not only magnetic pressures but also volumic Laplace forces can be calculated and exported to OptiStruct to compute mechanical stresses.

Efficient power busbar design using Flux PEEC
The PEEC (Partial Element Equivalent Circuit) method is now directly available in Flux. Because this solver does not need any meshing of the air surrounding the parts, it is much more efficient than the finite element method to deal with sets of long or flat conductors. It is the tool of choice for the design of power busbars. Resistances, inductances and parasitic capacitances of conductors can be quickly computed and extracted for circuit simulation. Current, power or force densities distributions are natural outputs that can be used with thermal or structural solvers to analyze respective temperature distributions or mechanical stresses in the bars.
