Dynamical mesh adaption for two-dimensional reactive flow simulations
Abstract
The most recent developments on an adaptive refinement-unrefinement method aimed at constructing a time-dependent unstructured finite-element triangulation for the simulation of stiff unsteady 2D flows are presented. The main features of the adaptive procedure and address the question of choosing the criterion which governs the refinement and unrefinement decisions are described. Then the basic conservative method used to discretize the reactive flow equations on the adaptive triangulation is presented and the problem of defining a numerical scheme which preserves the positivity of all mass fractions on the adaptive mesh is discussed.
