What's new in Altair Flux 2021
Altair EmployeeLet’s have a look at the key features and improvements of Altair Flux 2021 !
You will find also a video at the end of this post.
DYNAMIC MEMORY
Flux is now able to fully run using dynamic memory. No more questions for the user to know what memory size to be reserved. This is true when running Flux in interactive mode, but also in batch mode when it is called from other software like Activate or HyperStudy.
NON-MESHED COILS DEFINITION IMPROVED
When defining a composed non-meshed coil to represent a complex winding path, the tool to make the coil description has been greatly improved, letting you manage the list of points in a very easy way. A gain of time when designing 3D windings of electric machines.
CALCULATING EFFICIENCY MAPS FOR SKEWED MACHINE WITH FEMT
FEMT is a tool that allows to automate the calculations of efficiency maps for electric machines. When using this application with the Skew module, it is now using the latest iron loss calculation possibilities which brings great computation speed-up. More flexibility is also brought, as the tool is no more limited to the representation of one pole of the machine.
3D DC DISTRIBUTION OF CURRENTS IN CONDUCTIVE REGIONS
In 3D, the source of the field can be a current flow through a conductive region with complex shape. In this situation, the first thing is to determine the DC current distribution in the conductor, before solving for the magnetic field. This has now been automated to make this type of modeling easier.
A NEW PARALLEL ITERATIVE SOLVER
Up to now, parallel solving was only available through the direct solver MUMPS. It is very efficient for small models but require a lot of memory when applying it to big 3D simulations. For those cases, Flux now offers parallel iterative solvers coming from the PETSc library, which reduce the memory requirements by an order of magnitude. In some situations, it also allows to reduce the solving time.
EXPORTING ONE FORCE PER TOOTH
A new option has been introduced in Flux when exporting data for vibration analysis of electric machines. You can choose to export the force distribution over the stator teeth, or to select a global force per tooth. The amount of data to be produced is then lowered and the vibration analysis will require less time to solve with quite acceptable accuracy.
AND ALSO
In this version, new colors have been added in Flux to make your model look a bit more realistic.
As in every new Flux version, new examples and new macros are published. An example showing showing how to perform multi-speed NVH analysis is provided and a macro helping the creation of 3D axial machines has also been added.
Improvement of the documentation is brought, with new images, a direct link to the examples from the documentation, and also now a direct online access (https://2021.help.altair.com/2021/flux ).
Another way to get information is to connect to the Flux community page and exchange about Flux in the forum, to take benefit of the experience of other users: https://community.altair.com/community?id=community_topic&sys_id=4a15651a1b9d0c50a028542d1e4bcb2d&table=sn_communities_topic
