Absorbing boundary conditions for curved surfaces #100

Closed kbai closed 8 years ago

kbai commented 10 years ago

I would like to set absorbing boundary conditions on a curved boundary surface but I don't know how to do that since it seems we can only define absorbing boundaries as x_min x_max y_min y_max which are planar bounding surfaces.

Feasible (using the normal to the faces), but would require significant changes in the code; would be time consuming to implement

komatits commented 9 years ago

Probably better to do that for PML than for older, paraxial ("Stacey"-type) conditions. See https://github.com/geodynamics/specfem3d_globe/issues/277 and https://github.com/geodynamics/specfem3d/issues/312

The curved surface can absorb nomal incidence perfectly. Thus we close this issue.
