Abstract
Efficient and robust massively parallel algorithms are used
to solve 3D reacting flow applications. An unstructured grid
finite element method is implemented in the code MPSalsa to solve
incompressible flow coupled with heat and mass transport.
A fully-coupled inexact Newton method with backtracking
in conjuntion with a parallel preconditioned Krylov linear
solver (Aztec) allow the direct calculation of steady-states.
The quick solution time enables the optimization of a Chemical
Vapor Deposition reactor model.
