Abstract:
We derive a posteriori bounds for $(V - \hat V)$ and its difference quotient ${(V - \hat V)_x}$, where $V$ and $\hat V$ are, respectively, the exact and computed solution of a difference approximation to a mildly nonlinear parabolic initial boundary problem, with a known steadystate solution. It is assumed that the computation is over a long interval of time. The estimates are valid for a class of difference approximations, which includes the CrankNicolson method, and are of the same magnitude for both $(V - \hat V)$ and $(V - \hat V)x$.References
