Here we provide and describe the codes that we have developed. We do this to allow others to use (part of) it, to extract ideas, to give us feedback, and to allow reproduction and checking of (published) results. If you use our codes, please honor our work by quoting the paper(s) related to the codes, as indicated.

We also provide links to codes and databases of other groups that we have found useful.

• Afivo and the related streamer simulation programs Afivo-streamer. Afivo stands for Adaptive finite volume octree. It is a framework for adaptive finite volume simulations, with a focus on simplicity. It features quadtree/octree AMR, OpenMP parallelization and a built-in geometric multigrid solver.
• streamer_1d Code for 1D discharge simulations with a particle-in-cell or fluid model
• particle_swarm A Monte Carlo swarm simulation tool, to compute electron transport data in arbitrary E,B fields. Developed by Jannis Teunissen and Anbang Sun.
• PumpKin: Pathway redUction Method for Plasma KINetic models, developed by A.H. Markosyan, A. Luque and F.J. Gordillo-Vazquez.
