Roadmap
Where 
is going
What we are building, release by release. There are no dates: each version ships when it is ready.
Released
Where we are
Every version stays available, with its notes.
- 1.0
First public releaseJune 2026
A first, preliminary version: magnetic simulation with FEMM, PCB and round conductors, and cores from TDK, Ferroxcube and Micrometals.
- 2.0
CAPACITISiM and SPICESiMOctober 2026
Electric field simulation, SPICE models with guaranteed passivity, Litz wire and up to 10× faster round-wire simulations.
- 2.1
SPICESiM in its own tab26 October 2026Latest
The model order is found automatically and the fit is shown live. Stop keeps every finished frequency, and core losses are computed element by element.
Version 2
Next releases, on FEMM
Each one builds on the results MAGNETISiM already gives you.
- 2.2
Peak flux density and core losses
Analytical peak flux density from every winding, including leakage, and improved analytical core losses.
- 2.3
Litz wire and permeability
Faster repeated Litz-wire simulations and a configurable fitting equation for permeability versus frequency.
- 2.4
CAPACITISiM experiments
Distributed excitation and experiment variants in CAPACITISiM.
- 2.4.1
Live results
Results that appear while a frequency sweep is still running.
Version 3
Elmer
Elmer joins FEMM as a finite-element solver: first in 2D, then in full 3D, then thermal.
- 3.2
Elmer 2D
A second finite-element solver in 2D, alongside FEMM.
- 3.3
Elmer 3D
Full 3D models for the cases a 2D model cannot capture.
- 3.4
Thermal analysis
Temperature rise from the computed losses, with Elmer 3D.
Version 4
A solver of our own
- 4.0
Magnetic and thermal, in 2D and 3D
A finite-element solver written for MAGNETISiM, built for speed.
Beyond MAGNETISiM
New tools in the family
They share the same design, so the numbers stay consistent from one tool to the next. No version numbers yet.
Enter your converter and its specifications and get construction options to take into MAGNETISiM.
