PyPEEC - 3D PEEC Solver

PyPEEC Banner

Important

PyPEEC is a 3D quasi-magnetostatic field solver with the following characteristics:

  • PEEC method with FFT acceleration

  • Representation of the geometry with 3D voxels

  • Multithreading and GPU acceleration are available

  • Fast with moderate memory requirements

  • 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

  • Can be used with Jupyter notebooks

  • Advanced plotting capabilities

PyPEEC solves the following 3D quasi-magnetostatic problems:

  • Frequency domain solution (DC and AC)

  • Conductive and magnetic domains (ideal or lossy)

  • Connection of current and voltage sources

  • Extraction of the loss and energy densities

  • 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 advanced boundaries conditions

  • No model order reduction techniques

  • Limited to voxel geometries

The PyPEEC package contains the following tools:

  • mesher: create a 3D voxel structure from STL or PNG files

  • viewer: visualization of the 3D voxel structure

  • solver: solver for the magnetic field problem

  • plotter: visualization of the problem solution
