Summary
PyPEEC is a 3D quasi-magnetostatic PEEC solver developed at Dartmouth College within the Power Management Integration Center (PMIC). PyPEEC is a fast solver (FFT and GPU accelerated) that can simulate a large variety of magnetic components (inductors, transformers, chokes, IPT coils, busbars, etc.). The tool contains a mesher (STL, PNG, and GERBER formats), a solver (static and frequency domain), and advanced plotting capabilities. The code is written in Python and is fully open source!
Capabilities
PyPEEC features the following characteristics:
- PEEC method with FFT acceleration.
- Fast with moderate memory requirements.
- Representation of the geometry with 3D voxels.
- Parallel processing and GPU acceleration are available.
- Import the geometry from STL, PNG, and GERBER files.
- Draw the geometry with stacked 2D vector shapes or voxel indices.
- Pure Python and open source implementation.
- Can be used from the command line or with an API.
- Advanced plotting and visualization capabilities.
- Compatible with Jupyter notebooks.
- Compatible with ParaView.
PyPEEC solves the following 3D quasi-magnetostatic problems:
- Frequency domain solution (DC and AC).
- Conductive and magnetic domains (ideal or lossy).
- Isotropic, anisotropic, lumped, and distributed materials.
- Connection of current and voltage sources.
- Extraction of the current density, flux density, and potential.
- Extraction of the terminal voltage, current, and power.
- Computation of the free-space magnetic field .
PyPEEC has the following limitations:
- No capacitive effects.
- No dielectric domains.
- No force computations.
- No advanced boundary conditions.
- No domain decomposition techniques.
- No hierarchical matrix techniques.
- No model order reduction techniques.
- Limited to voxel geometries.
The PyPEEC package contains the following tools:
- mesher - Create a 3D voxel structure from the geometry.
- viewer - Visualization of the 3D voxel structure.
- solver - Solve the quasi-magnetostatic problem.
- plotter - Visualization of the problem solution.
Warning
The geometry is meshed with a regular voxel structure (uniform grid). Some geometries/problems are not suited for voxel structures (inefficient meshing). For such cases, PyPEEC can be very slow and consume a lot of memory.
