Thanks Dr. Guddati. I would read it carefully.

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

reflection boundary condition

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?
