I am trying to do acoustic scattering of spherical waves by a rigid sphere

and examples. How can I simulate spherical waves in deal.II? Any hints would
be helpful.
Anne,
I don't know whether you want to solve these problems in a time or frequency
formulation, and what other requirements you have. The usual approach is to go
through the different parts of
https://dealii.org/developer/doxygen/deal.II/Tutorial.html
and find a program that is as close as possible to what you are interested in,
and then start from there. There are, for example, already programs that solve
the Helmholtz equation (step-7) and the time dependent wave equation (step-24,
with a simple absorbing boundary condition) and a problem that uses the PML
(step-62). So many of the building blocks you're interested in are already there.
Best
Wolfgang
