Issues Short description of the source problem resolved in this version
Data Import/Export context FX-15297 In the data Import / Export context, new options have been implemented for the computation of surface (dFmagS) and volume (dFlapV) force collections at nodes, in order to improve the accuracy of NVH simulations. One of these options is proposed by default and is the only one available in "standard" mode. To have access to all others, the user has to select the "advanced mode" in Flux supervisor settings.

In order to profit of these improvements, the data collections in an existing Flux project must be firstly deleted and then recreated.

For more details on these computation strategies, please refer to the user guide delivered with Flux setup.

Please note that these developments also solve the tickets FX-16597 and FX-16855.

Data Import/Export context FX-19703 The approach, available in the Import/Export context, for exporting forces computed in Flux projects to OptiStruct called "Global forces [RBE3]" allowing the user to export a global force (e.g. on teeth of an electrical machine) is now fully available in Flux accross all user modes (standard, beta and advanced). Please refer to Flux supervisor options for more details on user modes and on how to select them.

Data Import/Export context FX-14862 In the data import/export context, for the forces data collection dedicated to rotating machines, the computation cylinder radius can now be automatically determinated by Flux or - as in the previous versions - can be setted to a user value. This improvement is available for Flux 2D and Flux Skew.

Environment FX-19254 Before Flux 2021.1, during the opening of Flux Supervisor or Flux the corresponding splash screen remained in the foreground, even if the user selected another application (Outlook, Word or any other application).

With Flux 2021.1, this is no longer the case, the splash screen of Flux supervisor or Flux moves to the background if the user selects another application.

Environment FX-14359

Flux is now full and only available in 64 bits mode on Windows and Linux.

Environment FX-19255 For faces and volumes with the color gray, the overlay mesh displayed is also used the opposite color to gray, but always a shade of gray. With this shade of gray, it was difficult to distinguish the mesh on these faces and volumes.

A specific treatment has been made in Flux 2021.1, in order to change the mesh color when the faces and volumes have a gray shade, and thus distinguish correctly the mesh.

Postprocessing FX-18336 Now, in Flux 3D transient magnetic application, it is possible to display the isovalues of dLossV quantity which represent the loss density values over a volume region.
Solving FX-19194 On non-linear projects, the increment computation can need a lot of memory. This was blocking on very large projects and made them impossible to solve. An improvement of this algorithm for projects larger than 10 million nodes has been developed to allow the solving.
Solving FX-18329 A refactoring of the solution increment computation has been done. This impacts projects with non linear materials and results in a reduction of the time spent in the algorithm and can reduce the memory consumption.
Solving FX-16063 When a user was describing a problem with a great number of small regions (in terms of number of elements they contain), the solving time suffered. In this new version, major improvements to speed-up the solving were made for this kind of problem.
Solving FX-17100 For very small problems, a dedicated direct linear solver is used to avoid invoking extra processes for very small matrices where the solving is very straightforward.
Solving FX-18547 On some projects, it has been observed that the parallel integration can slow down when using more and more cores. The strategy has been changed to improve the load balancing between the cores and then reduce the integration time in parallel.
