Smilei

Smilei is an open-source electromagnetic Particle-In-Cell code for kinetic plasma simulation. It is designed for high-performance computing and can run on modern supercomputing architectures. The software is co-developed by physicists and computer scientists, which gives it both strong numerical physics capabilities and serious parallel-performance engineering. Smilei supports a wide range of plasma studies, including laser-plasma interaction, accelerator physics, space physics, and astrophysical plasmas. It uses a C++ core with Python-based input and post-processing workflows, making simulations both performant and configurable. Its main value is giving plasma researchers a collaborative, extensible, and high-performance PIC platform for large-scale kinetic simulations.
