PyPEEC is an open source 3D quasi-magnetostatic solver programmed in Python. PyPEEC is using an FFT and GPU accelerated version of the PEEC method and is, therefore, extremely fast. The tool contains a mesher (STL, PNG, and GERBER formats), a solver (static and frequency domain), and advanced plotting capabilities.

AI-mag is a MATLAB software (using also COMSOL and Python) for power electronic inductor optimization. The goal of this tool is to combine the accuracy of the Finite Element Method (FEM) with the evaluation speed of Artificial Neural Network (ANN). The software can compute 500000 designs per second with less than 3% deviation with respect to 3D FEM simulations.

MATLAB toolbox for modeling and optimizing power magnetics (inductors and transformers). Fast and accurate semi-numerical methods are used (mirroring method, skin and proximity losses, reluctance model, fringing field, core loss map, etc.). The complete code is object-oriented and can be easily extended with abstract classes.

This MATLAB library is a complete implementation of the magnetic mirroring method also known as method of images. This tool can compute magnetic field pattern, the inductance matrix, and the energy of 2D conductors surrounded by a magnetic core. This is useful for designing inductors and transformers.

This MATLAB library extracts the losses of a litz wire winding from the field patterns. The losses are computed in the frequency domain with Bessel functions. The field patterns can be extracted with any simulation software (e.g. COMSOL, ANSYS, OpenFOAM). This is useful for designing inductors and transformers.

This MATLAB/COMSOL library extracts homogenized material parameters for a litz wire. This means that a complex litz wire, which is composed of many strands, can be replaced with a homogeneous material. This virtual material parameters are defined such that the energy and losses match the stranded litz wire.
