Hi,
finally I had some time to set up a simple example where I solve an
elliptic problem using adaptivity with delaunay meshes. Here you find a
link to download it from my dropbox:

The zip contains the example with comme
Yes it was the version of Triangle in libmesh, I've seen that theres
something similar for 3D I think, Tetgen right? At the moment I'm happy
with 2D, since my research is not focused on meshes and space
adaptivity, nevertheless I can't have hanging nodes.
The code is quite large, theres a lot of

Hi, thanks for the hints.
At the end I did it with the Triangle library, its probably not very
performing but I'm not interested on that at the moment. The main
routines are the following
- save_mesh: it saves the current mesh (using
Mesh::copy_nodes_and_elements) and creates a system with

Adaptively, I assume?
Paul mentioned mesh redistribution, which can be surprisingly
effective for adapting into layers but which is ha

You can uniformly refine:

Hello,
I was wondering if theres an algorithm in libmesh that refines the mesh
without creating hanging nodes? If not, would it be difficult to
implement one?
Thanks
