Abstract

We investigate several existing interface procedures for finite difference methods applied to advection-diffusion problems. The accuracy, stiffness and reflecting properties of various interface procedures are investigated. The analysis and numerical experiments show that there are only minor differences between various methods once a proper parameter choice has been made.
