          Abstract

          The mathematical model of a chemical  equilibrium  problem  which
          describes  an  explosion  can be considered to have three stages:
          explosion, detonation and isentropic expansion.  These stages can
          all  be  modelled  as  fairly  complicated nonlinear optimisation
          problems.  We describe the development of  software  for  solving
          these  problems  ``in  the field'' and ``in the laboratory''.  We
          discuss how the design of the software has influenced the  model-
          ling  of  the  underlying  phenomena  using an approximate ``hard
          sphere'' model and how the mixing of solid and gaseous phases  is
          treated.
