Abstract:

Efficient procedures for time-stepping Galerkin methods are considered for approximating the solution of a coupled nonlinear system with nonlinear Neumann boundary conditions. Possible model systems are shown for describing the miscible displacement of one incompressible fluid by another in a porous medium when flow conditions are prescribed on the boundary. The procedures involve the use of a preconditioned iterative method for approximately solving the different linear systems of equations arising at each time step in a discrete-time Galerkin method.
