Agenda

Present: RNH, RCK, DAH, PHJK, SV, DRS, LM, JDB, CW, CJC

Apologies: NB, KS

RCK

FIAT quadrature degree fields done for some elements.

DAH: someone has to be able to inform the UFL elements of their degree.

Stepping stone proposal towards element oracles: visitors get mapping that takes UFL elements into extra things. This doesn't put a hard dependency in UFL on anything else.

Firedrake 2021: online

Some kind of multi-afternoon thing to catch the US crowd. Not research talks, but posters + panels?

RNH: Unlock slack history

Has anyone got some spare money sloshing about that could be used to unlock the slack history? Might save a fair bit of time in certain occasions. (Fyi RNH == Reuben Nixon-Hill - formerly minuted as RWH)

DAH: Somewhat expensive (although Jack points out https://slack.com/intl/en-gb/help/articles/206646877-Slack-for-education)

DRS: Extruding functions

Ed Bueler made the PR -- makes assumptions about node ordering that are worth talking about

Node ordering for Base x R is defined to work.

RNH: Strange test failures

tests/regression/test_aw.py::test_aw[conforming] is failing on https://github.com/firedrakeproject/firedrake/pull/1867 and https://github.com/firedrakeproject/firedrake/pull/1884 which don't touch the relevant code

LM: Can anyone reproduce these fails in the Jenkins-based docker container?

DRS: NASA proposal call

DRS suggests expanding the demos to cover more geosciences data. Connecting to remote-sensing is a good idea.

Data assimilation?

DRS: to write a letter of intent.
