SPECFEM and underwater acoustics

#1

At one point work was being done to make SPECFEM usable for underwater acoustics problems. Is this still continuing? If so, is there any chance of a webinar on its use for this application?

#2

I’m trying to get specfem to work on atmosphere/ground model using an acoustic source (so similar to the underwater example) but am getting an error about using an acoustic source. I hope you get help soon!
