I am planning on using finite difference coding to solve a wave equation. The domain is a rectangular domian with wave reflection on the boundaries. Does anyone know how to set the reflection boundary condition?

Continued Fraction Absorbing Boundary Condition

Hi Wei,

You may want to look at our recent work on absorbing boundary conditions for FEM: http://www4.ncsu.edu/~mnguddat/Publications/CFABC_Polygon.pdf

A simple alteration of the boundary condition should provide an effective ABC for FDM. Hope this helps.

Cheers,

Murthy
