What's new in Altair Flux™ 2021.1
Altair EmployeeLet’s have a look at the key features and improvements of Altair Flux™ 2021.1 !
EASIER DEFINITION OF COILS
Windings are essential parts of 3D simulation models to define current paths in space and sources of the magnetic field. They are often of complex shapes like in electric machines, for example in the case of hairpin windings. In Flux™ 2021, improvement have been brought when defining them as non-meshed coils. In the new version, their modeling as meshed coils is also more efficient, letting the user more freedom to define them, supporting varying cross sections. It allows importing the coils from CAD files and meshing them in a more seamless way. To help also the definition of this key part of the modeling, the GUI used to define coils has been reworked for more clarity, especially concerning how copper losses are modeled. The associated documentation clearly explains the various models that are available and how to use them in Flux.
E-Motor NVH
Special efforts have been made in the latest versions of Flux to allow calculating and exporting excitation forces that can be used to compute the vibration and noise of electrical machines. New options have been added for the calculations of forces for increased accuracy and Flux can also now determine automatically the cylinder on which to compute the forces for radial machines. Some automation has also been created to help you create CSV files containing global forces per teeth that can be used by external software for electric powertrain NVH analysis.
AND ALSO
Improvements in the solver have been made to accelerate the integration phase during the computation of the matrix system, using a better parallel strategy. For very large models, memory requirements have been lowered when solving non-linear models.
To help with the export of data for system simulation, a macro that creates look-up tables in the d-q frame from a transient model has been added.
In the newly provided examples, there is one concerning the modeling of a switched reluctance machine. It is now completed with an optimization study to maximize the motor efficiency, as well as a thermal study, in which CFD computations are done to assess the heat transfer coefficients to be used in a Flux thermal computation.
A new example is now provided to show how Flux is able to evaluate the magnetic signature of a vessel.

Thank you very much for sharing this notes. I have always wondered why there are few number of examples and tutorials for Electric applications such as electrostatic and steady state AC electric. Does this new release have more info or notes or guidance for Electric applications?
Also, Most of the error messages in FLUX are unintuitive and difficult to understand. An error guide of the sorts would be greatly helpful.

Could any one comment on why does Altair FLUX have few examples for electric applications compared to magnetic applications? Please point me in the right direction if FLUX infact has good examples for electric applications.
