A direct method for solving the Boltzmann equation. (English) Zbl 0811.76050

Summary: A numerical method for solving the Boltzmann equation is proposed. This method is based on a finite difference scheme for the approximation of the collision kernel and on a finite element scheme for the transport phase. The properties of the Boltzmann equation are also satisfied in our method.
