Improvements

Issues	Short description of the source problem resolved in this version
Data Import/Export	SLVFX-35248	When exporting force data collections to an OptiStruct input file, it is now possible to limit the exported loadcase to the global one only.
Examples	SLVFX-36411	Add informations in the activate part for the tutorial "Flux - Twin Activate : Induction motor scalar control" to select which Flux version is used by Twin Activate. In the document of the tutorial, one step has been added at the begining of the Twin Activate part: Configure the path of the Flux to use in the preference of Twin Activate. Added in Flux 2025.
Examples	SLVFX-35219	In the tutorial "Translating motion 3D", the description of Advanced soliving options for the case2 has been updated and simplified to be consistent: - replace [No State variable set to 0] (does not exist) to [With the previous step] - remove the part corresponding to [Project Saving frequency] (no modification is required in the solving scenario) The updates have been done in Flux 2025.
Examples	SLVFX-35607	Update of the tutorial "Flux-Compose: Induction machine" 2D. The steps describe in the PDF document about "Activate server and API" is not necessary anymore. The corresponding slide has bee deleted in Flux 2025.
Postprocessing	SLVFX-36121	When creating 3D curves dedicated to rotating machine with a project using symmetry and/or periodicities, it is now possible to select a time interval representing the same fraction of a full turn period. The time signals will then be automatically duplicated to represent the overall turn.
Solving	SLVFX-34217	Flux Skew projects containing a large amount of solid conductor regions to model hairpin coils suffered from very slow operations during the extrusion of the geometry from the 2D view to the 3D representation. Flux internal algorithms have been improved to speed-up these operations.
Solving	SLVFX-35365	From Flux 2025 version, Intel Pardiso solver which was already hidden from the GUI and thus was only available through the Python command, has been completely removed from the possible options for solving the linear systems and it is consequently no longer available. When running the Python command with Intel Pardiso solver selected, Flux 2025 will display a warning message and switch the linear system solver type to "automatic".
Solving	SLVFX-34372	Up to and including Flux 2024.1 and when parametric distribution was enabled, warnings and error messages from Flux secondary instances were not displayed to the main Flux output window. Starting with Flux 2025, users will receive notifications about any issues encountered during the solving process related to Flux secondary instances (which are hidden from view), as these messages will now be displayed directly into the main Flux output window.
Solving	SLVFX-31399	The Topology Optimization feature, introduced in Flux 2023.1, was initially limited to "Magnetic non conducting regions". With Flux 2025 electrical machine designers can now apply Topology Optimization on "Laminated magnetic non conducting regions", thus enhancing design possibilities.
