Now I encounter another aspect of my problem that I don’t know how to tackle –
the matching conditions on the interface between the domains of the Stokes
flow in the droplet and around it.
Attached is a description of the problem in detail. I would be happy to know
if you or anyone else has some advice.
Typically, if you convert the equations into the weak form, you multiply the
equation by a test function and then you integrate (on each of the subdomains)
by parts. This yields terms that live on the boundaries of the subdomains,
including the interface between the subdomains. This is where you then need to
use the interface conditions.
In your code, this will lead to integrals over internal faces where these
faces sit at the interface.
