Hello, I am working on solving a Helmholtz-type problem, where I am using the PML method to simulate absorbing boundary conditions. Originally (before adding PML) I was using the complex GAMG preconditioner from the PETSc package, which was working fine. But now I am having a difficulty where the solver does not converge due to PML.
If anyone has any suggestions or experience, that would be greatly appreciated.
