<pre dir="auto" class="k9mail">Hi everybody,<br><br>when I look into the dune-function repository Merge requests and issue <br>list, I find lots of interesting approaches that are started but never <br>finished. Sometimes it looks promising, but no-one pushes this to a <br>final state. Maybe we could have a meeting after the summer to discuss <br>some points in person, to cleanup the list of proposals and issues, <br>maybe also define a better way how to work together/interact/review <br>proposals. A quick summary:<br><br>- Dynamic Order bases (!101: Dynamic order DG basis, !309: Lobatto shape <br>functions)<br>- Some proposals for new bases (!101, !309, !305: refined-LagrangeBasis <br>as alternative to P2 basis, !285: dynamic power node, scalar basis, ...)<br>- There are some ideas/discussions to simplify/restructure the pre-basis<br><br> * blocking structure: #54, #53, (!216, !217), !239<br> * adaptivity: !101, !128, !248, #51, #56, #62<br> * general cleanup/simplification/restructuring: !308, !217, !216, <br>#31, #37, #44, #46, #53<br><br>- What about Parallel bases? Using global index sets from dune-grid, or <br>global idsets for identifying unique orientation of edges. Global <br>identification of DOFs? What about an idset similar to the grid idset <br>but for basis functions?<br>- Additive composition of bases?<br>- Dynamic nodes are recently added to dune-typetree: What needs to be <br>done to make this work with dune-functions? (!285) Some <br>requirements/guanrantees might have changed.<br>- There are some topics asked for for years, like derivatives in <br>discrete global basis functions. (#25, #40, !57, !188) There are some <br>initial proposals. Why is this never included? What is missing?<br><br>What about an online meeting at the beginning of October. Maybe we can <br>also form some small groups locally in presence (e.g. in Dresden, <br>Berlin) and make a hybrid meeting. What do you think?<br><br>Best regards,<br>Simon<br><br><div class="k9mail-signature">-- <br>Dr. Simon Praetorius<br>Technische Universität Dresden<br>Institute of Scientific Computing<br>phone: +49 351 463-34432<br>mail: simon.praetorius@tu-dresden.de<br>web: <a href="https://tu-dresden.de/mn/math/wir/das-institut/beschaeftigte/simon-praetorius">https://tu-dresden.de/mn/math/wir/das-institut/beschaeftigte/simon-praetorius</a><br><br><br></div></pre></blockquote></div></body></html>
