Hi Ben,

I assume what you are interested in are the effects these waves have on something within the simulation domain. There isn't code (I know of) in the toolkit that could readily produce data like this. Thus, at the very minimum, you would need to write some code (a new thorn most likely) that does this; providing a boundary condition for such an incoming wave. I cannot say more than that, as that really would depend on the details of what you plan to do.

I am also curious about permeating a volume with a bispinor field.  Is there a package that I would have to add?

Again, I doubt something like that exists already, sorry.
