Good morning NGSolve community
I've been reading through the documentation and tutorials of NGSolve to see if it's possible to couple FEM with a boundary integral method in curl-curl Maxwell's equations (i.e. to simulate my computational FEM domain embedded in free-space, with an incoming wave-field).
It looks like all the basic tools are probably there in the Python interface (e.g. Trace() to get the right basis functions), but I'm not sure how to go about forming the double surface integrals/dense matrix part. Is this something already implemented, is it hackable, or would it require more C++ programming? Admittedly, I'm asking this having only had small play with NGSolve so far!
Alternatively, is there another way to set up this problem more suited to NGSolve that I may be overlooking?
Many thanks,
Francis
