Figure 1: Three distribution functions in different space points of a computational domain for a re-entry problem
Figure 2: Support of a distribution function f(x, .): the distribution (in black), its corre- corre-sponding Maxwellian (in blue), and the correcorre-sponding support based on the bulk velocity u and the temperature T .
Figure 3: Three different distribution functions and a global grid that satisfies (7)-(8): the bounds are given by the largest distribution, the step is given by the narrowest distribution.
Figure 4: Three different distribution functions (top), the corresponding uniform Carte- Carte-sian velocity grid (middle), and the grid locally refined in the support of the distributions (coarsened elsewhere).
