Dear Wen,

I agree that level_set implementation is not well documented in Getfem.
See anyway the page

Levelset are simply some scalar field defined on a mesh. Each level-set object has in fact two scalar fields. The primary level set and a secondary one. The secondary is optional. I tserves to limits the domain of the primary level-set. It comes from crack propagation approximation. See for instance the paper: Moës N, Gravouil A, Belytschko T. Non-planar 3D crack growth by the extended finite element and level sets. Part I: mechanical model.International Journal for Numerical Methods in Engineering 2002.

I am interested in crack propagation problem. Now I am trying to understand how levelset is implemented in getfem++ but it is very hard to understand with only limited commends. So I am wondering whether you have any good reference to recommend that could help understanding. Thanks.
