Numerical Analysis Seminars: The optimal compact finite-difference scheme for the diffusion equation with flow

Presented by Ron Smith (Loughborough),

14 May 2001 00:00 in CM105

A method for quantifying the solution error in compact finite-difference schemes has been used to design optimal and near-optimal schemes for progressively more complicated decay/advection/diffusion problems. The new schemes achieve given levels of accuracy with larger time steps and wider grid spacing. The required computational resources can be as small as 0.001 of traditional schemes.
