about far field bounary condition

January 6, 2004, 20:13

hi every body . is far boundary condition treatment depends on which numerical scheme will be use ?

I heard that if the scheme is upwind scheme it is enough to use initial boundary condition ( free stream condition ) as far field boundary condition. for example when using two dimensional unsteady euler equation to solve steady one.

Characteristic boundary condition is commonly used.

Thanks versi for reply Do you know some good reference about Characteristic boundary condition?

See, for example, the following review paper on non-reflective boundary conditions:

Givoli, 1991, Journal of Computational Physics, vol. 94, page 1.
