In time-domain wave problems, PML (Perfect Match Layer) serves as an excellent artificial boundary, capable of addressing the pseudo-reflection phenomenon caused by truncation boundaries. Is it possible to implement this artificial boundary in FreeFEM? Actually, I noticed that several friends have mentioned PML here, but it seems that no one can solve the related problems.
The problem with the PML method is your a lot of case,.
They is no problem to do PML with freefem++, and some exemple use PML.
Thank you for your response. Where can I find such a case?
find PML in examples.
you can see FreeFem-sources/examples/ffddm/Helmholtz_geophysics.edp at develop · FreeFem/FreeFem-sources · GitHub
Thank you very much!
