Dear Andy, The primary level-set function describes the geometry of the crack : its 0 level-set should contain the crack itself. The secondary level-set function describes the crack front, the crack correspond to the part of the domain where the level-set function is non-positive. This is mostly explained for the 3D case in the paper. Gravouil A, Moës N, Belytschko T. Non-planar 3D crack growth by the extended finite element and level sets. Part I and II. International Journal for Numerical Methods in Engineerin, 2002. If you want a model for the enrichment and the adaptation of integration for the 3D case, you can have a look to the program /contrib/delaminated_crack/delaminated_crack.cc Best Regards, Yves Le 21/06/2016 04:12, Andrew Roberts a écrit :
