Welcome
User guide
The user guide gives information about principles and how to use Altair® Flux® 2026.
What's New
See the release notes of the last and previous versions, with the necessary information on new features.
"How to" Documents
See a list of documents to understand how to use certain features.
Altair Flux Videos
Several youtube videos about how to use Altair Flux and several tip and tricks
Flux Supervisor
The Flux supervisor allows to run projects, examples, pythons scripts; to configure user preferences; to access tools...
Flux
Flux is a finite element software for low-frequency electromagnetic and thermal simulations. Both, 2D and 3D solutions are available...
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.
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 and SKEW with all available documents, as well as all project and python files.
Flux in SimLab Examples
See the list of SimLab examples using the Flux and Mipse solvers, with all available documents, *.slb databases, and all script files.
Mementos
See a list of Memento documents to understand certain Flux features.

PyFlux Documentation (Beta version)
This documentation deals with the Jython script used in Flux and allows to understand the various structures of entities and functions, and use it in user scripts for example.
Flux installation guide
This document provides instructions for Flux installation on supported platforms.
Flux Starting Guide
Several short videos to start with Flux.

Since version 2026, Flux 3D and Flux PEEC are no longer available.

Please use SimLab to create a new 3D project or to import an existing Flux 3D project.

Please use SimLab to create a new PEEC project (not possible to import an existing Flux PEEC project).

/!\ Documentation updates are in progress – some mentions of 3D may still appear.

FindOutSupplyForGivenTemperature.PFM

Description

Find out the value of the supply given a targeted temperature at the end of a predefined scenario.

Note: For more details about this macro, consult this additional document

Input

The scenario to solve
The targeted temperature (in degree Celsius)
The sensor allowing to compute the temperature
The I/O parameter to be varied (VOLTAGE in this example)
The maximal value of the input parameter
Precision expected on the temperature (in degree Celsius)
The maximum number of iterations allowed to find the value of the supply that gives the targeted temperature

Output

The Flux project solved
A text file created in the working directory containing iteration done to find the value of the supply
