List of Flux 2022.1 new features
New features dealing with Environment
| New features | Description |
|---|---|
| New Trademark | The Trademark has been changed.
Altair Flux™ become
Altair® Flux®. The modification has been done in:
|
| Migration to Java 11 | All applications Flux, Flux Supervisor, Materail Manager, FEMT used now Java 11. |
| Update of log4j | Update of log4j from 1.2.17 to 2.17.1 due to security vulnerability. |
New features dealing with Mechanical Set
| New features | Description |
|---|---|
| Six Degrees of Freedom |
A new type of Mechanical set has been implemented to able to take into account the Six degrees of freedom of a motion. It is now possible to apply a rotating and translating movement to the moving mechanical set at each resolution step. Three workflows are possible:

New features dealing with Physics
| New features | Description |
|---|---|
| Speed-up of iron losses computing in post-processing while using parametric distributing solving. | While solving a project with several varying parameters with the parametric distribution (CDE for Windows and Distribution manager for Linux), the computation of iron losses in post-processing using the modified Bertotti model or the LS model has been drastically accelerated. Note that it also affects the Import / Export context and that every data collection that will be created before solving will be collected during solving (e.g. forces data collection for a multi-speed distributed scenario). |
New features dealing with Solving
| New features | Description |
|---|---|
| Parametric distribution for Linux | The establishment of a parametric distribution in Flux for Linux OS is now possible. The distributed computing allows the user to save computation time while distributing several independent configurations of a same Flux project. For example a Transient Magnetic project may be distributed regarding differents values of parameters such as the geometrical parameters (size, shape etc...) or physical parameters (supply current values, speed...) varying in the scenario. |
| Upgraded Compression solver for inductive computations in Flux PEEC |
The Compression solver provided in Flux PEEC for inductive calculations has been upgraded in version 2022.1. The new implementation benefits from improved matrix compression techniques that may significantly reduce the memory requirements and the solving time in the case of large Flux PEEC projects. Full backward compatibility is assured for projects that were saved or solved with the previous implementation. |
New features dealing with Flux e-Machine Toolbox ( FEMT)
| New features | Description |
|---|---|
| Switch from User to Dynamic numerical memory mode and vice versa inside FeMT | It is now possible to change the numerical memory mode used to run the test inside FeMT. |
| Distributed computing available on Linux | On Linux, it is now possible to run a test by activating the local distribution. |
| Run tests through PBS (by manual Export / Import) |
To save computation time, it is now possible to run tests through PBS. |
| New extrapolation approach for efficiency maps | There is now a new map extrapolation method to obtain correct values near map borders and thus avoid obtaining non-physical values, such as negative Irms values. |
Updated/New macros
| Updated macros | Description |
|---|---|
| Find_rotor_angle_3D.PFM (update) |
This macro now supports complete motor models without periodicity. |
| circuit_collector_2D.PFM (update) |
Some terminals were not correctly connected when you open the circuit editor. The macro has been updated to correct this issue. |
