All machines

When creating a Flux skewed project, issue with project

=> if you save and close your project, it is impossible to open and solve it

=> if you solve the project, it is impossible to delete results and rerun the project (ref.: FXM-15638).

A motor created with the Japanese language cannot be opened

When we create a catalog and a motor with the Japanese language enabled, the catalog of the motor cannot be opened if the user switch back to the English language (ref.: FXM-15827).

The memory preferences are not kept consistent with the execution of a long test

When several instances of batch are run in parallel, we regularly observed that the memory preferences are not kept consistent between two consequent executions of Flux Jobs (ref.: FXM-15777).

Full geometry is provided although periodicity would be possible

While exporting a project to Flux 2d or Skew, the periodicity is multiplied by 2 when the number of represented poles is odd and different from 1 (ref.: FXM-15566).

Hairpin architecture

Solving tests or exporting projects to Flux is not allowed when the Hairpin winding is built with two layers. This will be fixed for the next version (ref.: FXM-15516).

Unable to execute test with Skew enabled in certain machine models (SMPM-OR)

Sometimes, for certain kind of machine, it is not possible to execute test with a skewed topology. In such cases, the error message contains the following message: “Please decrease the "Relative epsilon for distance between Points” (ref.: FXM-15475).

Export to FeMT with too long output path

The Flux script crashes when the output path for FeMT export is too long (ref.: FXM-15471).

Excel export does not work for the test Model - Maps

For the Synchronous machines with Permanent Magnets – SMPM (ref.: FXM-15465).

Fault in the coupling FluxMotor-HyperStudy

An error in the FluxMotor process doesn't stop the HyperStudy execution (ref.: FXM-15402).

Script Factory does not stop correctly

This occurs if the FluxMotor process has been killed externally. Then, ScriptFactory is not able to get back to a valid state, neither automatically nor after a kill of the process (ref.: FXM-15140)

Bad meshing while representing wires inside the slots

When exporting a project from FluxMotor to Flux 2D, the mesh in the slot can be sometime very bad in the region surrounding the represented wires inside the coil conductors (ref.: FXM-15151).

Issue with exported Flux Skew projects

After exporting a Flux Skew project, if the user solves the project, deletes the results, and then solves again, the running of the project fails (ref.: FXM-15075).

Null values are not well managed while designing the Frame and shaft

Null values are allowed for designing the housing, bearing or shaft dimensions, but this leads to the wrong thermal analysis. It is highly recommended not to use null values for the considered inputs (ref.: FXM-14705).

Error while opening a motor (2020.1) with null shaft extension

Opening a motor built with version 2020.1 (or older) with a null shaft extension leads to an error. With new versions, a null shaft extension is forbidden (ref.: FXM-14684).

The interwire space is not well defined.

The resulting value of the interwire space applied in the finite element model is twice the value set in the user inputs (ref.: FXM-14672).

Air material properties are wrong for high temperature

This issue impacts our internal computation processes during transient thermal solving. Indeed, some iterations involve very high temperature (more than 3000 °K) according to the Newton Raphson non-linear solving method. During the resolution, this can lead to negative conductivity and viscosity, which may make the computation fail (ref.: FXM-14465).

Note: In case of a problem, an “Air material” with the right parameters can be provided.

When an IO cannot be loaded, the test results are not accessible

When an IO cannot be loaded, the whole process that loads all the test results is stopped. As a result, no test is visible, although the issue may concern one result in a particular test (ref.: FXM-13941).

A wedge and/or inter-coil insulation region leads to a wrong slot equivalent thermal conductivity

The slot radial thermal conductivity, which is automatically provided by the FluxMotor® in "Cooling-Internal" context and used in all thermal tests, is wrong if the slot contains faces "wedge" or "inter-coil insulator" (ref.: FXM-13896).

Power electronics and coupling with HyperStudy®

For tests where settings "Electronics" is available, data like power electronics stage, maximum efficiency, and its rated power can be selected for generating a connector for HyperStudy®, but it should not be.

In the Export-HyperStudy® area, when the selected test is “Working Point, T-N”, the settings of “Electronics” - "Max efficiency", and "Rated Power" - are exported even if the associated option is not selected (ref.: FXM-13726).

Winding environment – MMF computation

The Counter-Clockwise sequence (MMF computation) is not considered in the Altair® Flux® model, which one can export. Only the clockwise phase sequence is considered (ref.: FXM-10280).

Using "phase sequence" set to "Counterclockwise" leads to wrong results in tests (ref.: FXM-13358).

Flux density isovalues

When a skewed topology is considered (Synchronous machines or induction machines), the flux density isovalues, the vector potential isolines and the rotor bars current density isovalues are not displayed (ref.: FXM-12564).
