Sound-Hard problem with ABC boundary conditions - Reproduce the experiments in Galkowski #14

Closed pescap closed 2 years ago

pescap commented 2 years ago

Reproduce the experiments in LOCAL ABSORBING BOUNDARY CONDITIONS ON FIXED DOMAINS GIVE ORDER-ONE ERRORS FOR HIGH-FREQUENCY WAVES.

Innner: Circle Outer: Circle

Compare the ABC solution to the exact solution.

Inner: Butterfly-shaped object Outer: Circle

Inner: Polygon Outer: Circle

These experiments are very similar to: https://github.com/pescap/ScattPINNs/blob/main/examples/forward/Helmholtz_Sound_hard_ABC_2d.py

@ArtemioA, you just need to change the geometries, and set the physical parameters properly. Filename:

Helmholtz_Sound_hard_Exp114.py helmholtz.2d.sound.hard.abc.exp114.rst

and so on.
