Abstract [en]

We investigate several existing interface procedures for finite difference methods applied to advection–diffusion problems. The accuracy, stiffness and reflecting properties of the various interface procedures are investigated.

The analysis and numerical experiments show that there are only minor differences between the various methods once a proper parameter choice has been made.
