Abstract : A numerical method for the solution of the nonlinear Boltzmann equation of hard sphere molecules is developed, in which approximations are made only in the sense of numerical truncations. The distribution function is evaluated at a threedimensional grid of distinct velocity points. A five fold Gaussian quadrature is performed to evaluate the five derivatives at these points. The distribution function is then evaluated at t sub o + delta t by solving a system of first order ordinary differential equations. In the nonlinear case the grid is no longer closed, and the procedure to circumvent the difficulty is described. This technique is applied to the problem of nonlinear, homogeneous, pseudoshock relaxation. (Author)
