HYB SIMULATION PLATFORM HYB (How You Been) is a versatile C++ quasi-neutral hybrid (QNH) plasma simulation platform for the solar wind and plasma interactions of celestial bodies. The HYB code is developed at the Finnish Meteorological Institute and the Aalto University. The HYB code and tools are distributed under the GPL v3 open source license by the Finnish Meteorological Institute. The latest version of HYB can be downloaded at: https://github.com/fmihpc/hyb Folders: sim/: The HYB simulation code tools/: Tools to analyze HYB output files HYB CODE HYB is a 3-dimensional code and uses Cartesian or spherical simulation mesh. The Cartesian mesh can be hierarchically refined to adjust the grid cell size within the simulation domain. HYB is a highly optimized and memory efficient serial code designed for the Linux environment. In the QNH approach positively charged ions are treated as macro particle clouds moving under the Lorentz force and electrons are a charge-neutralizing, massless fluid. The electron momentum equation (Ohm's law) defines the electric field. Faraday's law is used to propagate the magnetic field on the grid cell faces. Ampere's law gives the electric current density. A Yee type staggered mesh keeps magnetic field divergence-free. ACKNOWLEDGEMENTS We request acknowledging and citing the original code when publishing or presenting results from HYB. The HYB developers are open for scientific collaborations and further development of the code.
