The level-set object is represented by a primary level-set and optionally
a secondary level-set used to represent fractures (if p(x) is the primary
level-set function and s(x) is the secondary level-set, the crack is
defined by and
: the role of the secondary is to determine
the crack front/tip).
note:
All tools listed below need the package qhull installed on your
system. This package is widely available. It computes convex hull and
delaunay triangulations in arbitrary dimension.
LS = gf_levelset(mesh m, int d[, string 'ws'| string f1[, string f2 | string 'ws']])

LS = gf_levelset(mesh m, int d[, string 'ws'| string f1[, string f2 | string 'ws']])
Create a levelset object on a mesh represented by a primary function
(and optional secondary function, both) defined on a lagrange mesh_fem of
degree d
.
If ws
(with secondary) is set; this levelset is represented by a
primary function and a secondary function. If f1
is set; the primary
function is defined by that expression. If f2
is set; this levelset
is represented by a primary function and a secondary function defined
by these expressions.
