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.
Flux PEEC
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.
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, 3D, SKEW and PEEC with all available documents and all project and python files.
Flux in SimLab Examples
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.
Mementos
See a list of Memento documents to understand certain Flux features.
Macros
Flux proposes several macros enabling doing actions that are not yet implemented in Flux.
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.
