Flat quadtree
Point charges (3D Coulomb) or line charges (2D Poisson) at any targets, by Barnes-Hut tree walk or direct sum.
tree-d-3d
Tree Dynamics in 3D. Barnes-Hut trees and fast multipole methods for charged particles, on NumPy, CuPy or Apple GPUs.
tree-d-3d stands for Tree Dynamics in 3D. For now the particles move in a plane, with the 3D Coulomb field of point charges or the 2D field of line charges. Full 3D, on an octree, is planned.
What is included
Section titled “What is included”Fast multipole method
O(N) fields of line charges with a dual-tree traversal and complex multipole expansions.
Simulation
Second-order time integration with a uniform magnetic field, absorbing walls and objects, and cached fields.
Electrodes
Conductors at prescribed potentials by the panel method, built from any 2D simgeometry shape.
Kernels
Every kernel in Pyccel, NumPy, CUDA and Metal, with the same arguments.
