I'm trying to solve an elliptic problem with discontinuous material
properties. The values can vary by ~ 10^5, so the system is ill-conditioned.
Currently I'm using various other FE solvers that don't deal well with this
conditioning.
The first picture in the deal.II website (http://www.dealii.org/) is the
included image. It appears also in the gallery
(https://github.com/dealii/dealii/wiki/Gallery). My solutions looks similar to
this. I was hoping somebody in the community could point me to any examples
that solve similar problems, or the code that produced this.
If I recall correctly, the code that produced this file used the immersed
boundary method. I don't remember who wrote the code, but remember that it is
not part of either the tutorial or the code gallery -- sorry.
