MAGNETISiM releases

MAGNETISiM 2.1

Mon, 26 Oct 2026 00:00:00 GMT

New SPICESiM tab in Results: generate and export the SPICE model with a live console and live plots (the N×N error grid, the selected cell with |Z| and phase, and the pole map). It runs in the background and can be cancelled at any time without writing anything.
Automatic order search for Vector Fitting: instead of choosing the order, set the Maximum model error (2 % by default) and the Maximum model order; SPICESiM finds the lowest order that meets the error. Fitting is faster and more accurate (relaxed Vector Fitting, solved block by block), and an optional Enforce reciprocity tick (on by default) exports a symmetric model.
Stop keeps what is finished: stopping a sweep (or closing the application while it runs) keeps and shows every frequency that had already finished.
“All” frequencies in Circuit Viewer and Power Loss, and an excitation Value that can be one number or one value per simulated frequency (comma-separated). The excitation and the winding grouping are saved with the project and come back when it is opened.
Clear warnings for input that cannot be used: any field that cannot be read (or is impossible, such as a frequency of 0) is shown in red with a one-line tooltip, and Run does not simulate until it is fixed. This covers Setup, Core, Windings, the folder settings and the wizards.
First start: the EULA is shown and must be accepted, then the folders are asked for. Each new portable version asks again.

CAPACITISiM: electric field calculation, fully refined and integrated into the simulator. Supports RZ, XYA and XYB analyses, including insulation layers between both flat and round conductors.
SPICESiM: multi-circuit support for accurate simulation of capacitive effects coupled to the magnetic model. Exported equivalent circuits are automatically checked and, if needed, corrected to guarantee passivity, so they run stably in circuit simulators such as LTspice or SIMPLIS.
Litz wire support: a new conductor type defined by strand radius, number of strands and packing factor. It is modeled as an equivalent homogenized material in magnetic simulations and as solid copper in electric simulations.
10× faster round-wire simulations: round-conductor simulations now take a tenth of the time, with no loss of accuracy.
Improved background simulations: keep working while simulations run, cancel running jobs at any time, and use Clean up to remove leftovers and invalid simulations. A new real-time console shows the solver’s progress step by step.

First public release, still preliminary: magnetic simulation of components with FEMM.
Windings: PCB and round conductors.
Core catalogs: TDK, Ferroxcube and Micrometals.
