Firedrake integration for the poisson problem

[florian98765]

Dear Andreas,
sometimes ago you commented on one of my firedrake issues, regarding coupling firedrake with some BEM library.
I would like to try to replace (extend) our current library with pytentials. Up to now, I managed to install meshmode as well as pytentials within our firedrake docker container.

The original plan was to use the code from the meshmode examples to_firedrake.py and from_firedrake.py. Before I start implementing I just wanted to make sure that this is still up-to-date, or if there is already some interface using the UFL external operators as reported within your publication.

best wishes and thanks for your help
Florian

Hi Florian, good to hear from you. We're actually developing this integration as part of a grant project, so there already exist some components (realized as Firedrake ExternalOperators) that you could use. As a disclaimer: That work is happening as we speak, so there are some aspects that are a bit in flux. If you're OK with that (and willing to tolerate the occasional code breakage that we'll help you with), we would love to have you as a user/guinea pig. :)

The easiest way to get this started might be if you join us on the #nonlocal channel on Firedrake slack.
