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.

Arrows: about

Displaying arrows

The (vector) spatial quantities can be displayed on various supports in the form of colored arrows as follows:

arrows color commensurate with the quantity modulus
arrows orientation indicates the quantity direction

Types of arrows

3 types of arrows are available:

arrows (available on different types of supports)
arrows on a path
arrows on boundaries

Supports

Supports for post processing are the following:

spatial group
2D grid
3D grid (only in 3D)
cut plane (only in 3D)

Spatial quantity

The spatial quantity depends on the activated physical application*.

The user can also use a formula with spatial quantities.

Note: * The detailed list of spatial quantities available for each physical application is presented in § "Result analysis" of each physical application.

Physical location

When support to display arrows is of the volume type (volume region), spatial quantity is computed in the inside of the region.

When support to display arrows is a surface support, it is often in interface between physical regions. The user can thus be interested in the computation and display of the spatial quantities on both sides of this interface, i.e. in each physical region in contact with this interface.

The user benefit from different computation and display options, depending on the support (Arrows: options).

Environment

The computed arrows are displayed on the chosen support and visualized in the graphic standard zone with the following item added:

a scale of values
a display option zone (arrows: options)

Note: the environment is the same for the display of isovalues, isolines and arrows


Zone	Function
Scale of values	Area comprising the scale of values calculated and displayed with the correspondence of the color shade. This scale can be displaced in the standard area, enlarged or reduced.
Standard graphic area	Area comprising the geometric view of the device with the displaying of the calculated isovalues.
Display options area	Area comprising the display options of the calculations of isovalues, isolines and arrows. Each type of calculation has an activable tab to permit to switch from the display options of the isovalues to the display options of the arrows.
