List of Flux 2022 new features
New features dealing with Environment
New features | Description |
---|---|
Merge of Flux and FluxMotor setups |
The Windows installers of Flux and FluxMotor are merged into one installer. As FluxMotor is not supported on Linux, the Linux installer contains only Flux. The supervisor of Flux have direct access to FluxMotor. The supervisor of FluxMotor have a direct access to Flux. |
Python API |
A Python API to drive Flux has been developped and is available in the installation directory : INSTALLATION_FOLDER\flux\Flux\Api\Python. For more informations about this topic, see the documentation dealing with the APIs. This API requires at least Python 3.0, the reference version is Python 3.5.4 and runs with Windows 64 bits and Linux. |
New features dealing with Meshing
New features | Description |
---|---|
Layers Mesh Generator improvements |
The "Layers" mesh generator type allows to model a skin effect at the boundaries of volumes. In additional, since this release Flux 2022, it is possible to specify for each face if the layers mesh generator should not apply. It is useful for instance for internal faces of a volume,where the thin layer is not necessary. |

Coil conductor regions with losses and detailed geometrical description |
This detailed description of the winding considers the proximity
and the skin effects in the Joule losses computation through
special homogenization techniques. Consequently, to set up this
model, Flux asks for a full description of the coil wires
through three templates:
This feature was already available in Flux 2D and Flux 3D Magnetic Steady State AC applications and is now available for Flux 2D Transient Magnetic application. The change application feature may be used to move from an application to another one. |
Foil coil windings |
A foil coil is a winding obtained from a thin, rectangular, metallic sheet folded in a spiral-like shape. This kind of coil design is common in electromagnetic devices such as power transformers and reactors. The current density in a foil-wound coil fed by a time-varying source depends on skin and proximity effects. Since the foil is usually very thin and made from a material with a high electrical conductivity, the skin effect along its thickness is negligible. On the other hand, the current density in each foil turn may vary along the axial direction of the coil as a function of both position and frequency. This behavior is specific to foil coils and influences the Joule losses developed in the coil. Thus, Flux now provides a new subtype of the coil conductor region with losses and detailed geometric description that implements a homogenization technique to represent this type of coil efficiently in its 2D Steady State AC application. Using this new coil conductor region subtype spares the user from representing each turn of the foil coil with an individual solid conductor region (linked to its corresponding FE coupling component in a complicated electric circuit). While this latter approach is also legitimate and rigorous, it is usually very time consuming to set up in Flux due to the elaborate geometry and the refined mesh required. Moreover, the solving time with the new foil-wound coil conductor region subtype is significantly reduced when compared to a solid conductor approach. |
