KINEBEC is a simulation code developed in C dedicated to classical and quantum Boltzmann equations in 2D and 3D in velocity. This code is based on spectral methods in velocity and can uses MPI, OpenMP or CUDA tools for speeding up its execution and for managing large data. More details about the involved numerical methods can be found in the following papers: * Mouhot & Pareschi: *Fast algorithms for computing the Boltzmann collision operator*, Math.
