Query about iteration for my design.
Hi, I am investigating the magnetic field strength of an array of magnet setup, and I have been messing around with the dimensions, shape, etc where I can iterate through parameters for my design. I would like to now iterate through different number of magnets in the system, by turning them on and off. My idea would be to,…

I’m trying to confirm and (if needed) change the geometric units used in the Flux modeler.
In Flux Supervisor my project is set up with metres as the base unit in the Units Manager. However, inside the Flux modeler environment, when I define a point at (0.15, 0, 0.05), the tooltip shows (150e-6, 0, 50e-6), which suggests my geometry is interpreted in millimetres and then displayed in metres. What is the correct…

Flux & Simulink co-simulation - variation of geometric parameters
Hello, does somebpdy know if it is possible to change parameters used in the geometric definition of a machine (e.g. the airgap length or the slot width) in Flux when using the co-simulation in MATLAB/Simulink? It is pretty easy to do in a solving scenario when just working in Flux. However I wanna use the solution data in…

Measurement of the flux density in a fixed distance away from the rotor
Hi everyone, thanks for your patience! I have performed measurements along the rotor axis (z-direction), where the sensor moved parallel to the rotor while maintaining a constant distance from its surface. I would now like to reproduce these measurements in a simulation. How can I evaluate the magnetic flux density at a…

Error in coupling Flux with Matlab-Simulink
I want to couple a Flux v.2025 project with Matlab/Simulink v.2023b. First, I got a .F2MS file from Flux, then I opened Matlab from the Flux Supervisor, and then I selected Flux Link block in Simulink library. Although the time step is the same in the two the softwares, I face the below errors: Error:An error occurred…

Is there a way to export a PNG of the geometry/Temperature isovalues map using terminal?
When I run Flux in the GUI, I can export the visual representation of the geometry or the heat map using printGraphicToFile(fileName=img_path, width=1280, height=1024). However, when I execute the same script in batch mode from the terminal, the image is not exported. Is there an alternative method to generate the PNG in…

Electric Motor Design with Topology Optimization and Non-Linear Mechanics
Designing high-performance electric motors isn’t just about maximizing torque or minimizing ripple — it’s about making sure the design can actually be manufactured and survive real-world stresses. That’s where topology optimization comes in. What is Topology Optimization? Topology optimization (TO) is a design method that…
