Dear Wen,
I agree that level_set implementation is not well documented in Getfem. See anyway the page http://download.gna.org/getfem/html/homepage/userdoc/xfem.html 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. Yves. Le 14/11/2013 17:04, Wen Jiang a écrit : > Hi, > > I am interested in crack propagation problem.
