Submitted by Wei Wang on Sun, 10/05/2008 - 00:46 reflection boundary in finite difference method 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? Murthy N. Guddati 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 Log in or register to post comments Tue, 10/07/2008 - 03:36 Permalink Wei Wang Thanks Dr. Guddati. I would 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,
