Hi Everyone,
I am experiencing an issue regarding PML in anisotropic media. I am interested in wave propagation in anisotropic elastic media thus the PML is also the same medium as propagation domain with anisotropic parameters. However, I never get convergence of results by changing the simulation size/PML size etc. I saw reflections from PML. I also did the simulations for isotropic media and everything works.
Does anybody know any issue regarding PML implementation in the case of anisotrpic media?
or Should I take care some additional degrees of freedom such as symmetries or strech parameter etc. for the implementation in the case of anisotrpic media?
Regards, Burak
