Here is a presentation of the Flux environment; the project management, the data management, the command language, the formulas and mathematical functions.
The construction of a Flux project consists of several stages: Geometry → Mesh → Physics → Resolution → Postprocessing; with the possibility to import a CAD file, a mesh, materials...
Flux allows to model different physical phenomena, and includes various applications (magnetic, electrical, thermal and thermal coupled).
Flux is coupled to a circuit context allowing to model the sources of the devices.Flux also allow to model the movement via a kinematic coupling.
Flux is able to couple with several softwares allowing to model mutliphysics phenomena.
Several dedicated couplings are implemented in Flux to, carry out vibro-acoustic studies, magneto-thermal studies and more.
Flux has predefined models for rotating machines via Overlays allowing to describe a geometry, a mesh and a physics adapted to the wished machine.
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.
Flux PEEC is a 3D modeling module dedicated to electrical interconnections of power electronics devices. It also provides RLC extraction and generation of SPICE-like equivalent circuits.
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.
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.
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.
FeMt is a application in Flux dedicated for Electric Machine which permits to compute and postprocess results like efficiency maps.
See the lists of examples 2D, 3D, SKEW and PEEC with all available documents and all project and python files.
See the lists of 2D and 3D SimLab examples using the Flux and Mipse solvers, with all available documents, *.slb databases and all script files.
See a list of Memento documents to understand certain Flux features.
Flux proposes several macros enabling doing actions that are not yet implemented in Flux.
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.
This document provides instructions for Flux installation on supported platforms.
Several short videos to start with Flux.
