This problem seems to be getting a lot of research lately. The problem being how to process PDEs on complex domains because meshing is a bitch. There seem to be a number of good approaches, NURBS Fea, this, Lawerence Livermore and Caltech just come out with a polygonal mesher.
I wonder how tractable and accurate they are from the solver side. Because generating high quality meshes really is a pain in the ass.
- person_of_color 6y agoWhy do we need to mesh them?
- wetmore 6y agoIn order to apply finite element approximation approaches.
- person_of_color 6y agoCan't you apply the model approaches directly?
- Minor49er 6y agoThe problem is gaining traction because it was used in the Covid 19 sim that was publicly released recently https://github.com/mrc-ide/covid-sim/blob/master/README.md https://github.com/mrc-ide/covid-sim/blob/master/README.md There was even a thread about it that made its way to the front page of HN yesterday but was flagged without an explanation https://news.ycombinator.com/item?id=23109211 https://news.ycombinator.com/item?id=23109211
- wetmore 6y agoI don't think they are very related.
- Minor49er 6y agoWhat else would cause the sudden interest?

- mkl 6y agoThis research would have been well underway before Covid-19 appeared. It's a very interesting area, and has been for a while. Just look at the neat pictures in the article! I did my PhD on mesh-free approximations in the 2000s, and this kind of research has been picking up steam for decades as people exhaust possibilities for meshing and gain computing power.
