Higher Order Discretisation of Initial-Boundary Value Problems for Mixed
Systems
R. Bodenmann and H. J. Schroll
Abstract:
An initial-boundary value problem for a system of nonlinear partial
differential equations which consists of a hyperbolic and a parabolic part
is taken into consideration.
Spacial derivatives are discretised by third order consistent difference
operators which are constructed such that a summation--by--parts formula
holds. Therefore, the space discretisation is energy bounded and algebraically
stable implicit Runge-Kutta methods can be applied to integrate in time.
Boundary layers arising from the artificial boundary conditions are
analysed and nonlinear convergence is proved.
