Level-set module¶

Description¶

Define level-set objects and cut meshes, integration method and finite element method with respect to one or several level-set.

File(s)	Description
`getfem_level_set.h` and `getfem_level_set.cc`	Define a level-set function (scalar field defined on a Lagrange fem) with an optional secondary level-set function.
`getfem_mesh_level_set.h` and `getfem_mesh_level_set.cc`	Cut a mesh with respect to one or several level-sets.
`getfem_fem_level_set.h` and `getfem_fem_level_set.cc`	Define a special finite element method which depends on the element and which is cut by one or several level-sets.
`getfem_mesh_fem_level_set.h` and `getfem_mesh_fem_level_set.cc`	Produces a mesh_fem object with shape functions cut by one or several level-sets.
`getfem_mesh_im_level_set.h` and `getfem_mesh_im_level_set.cc`	Produce a mesh_im representing an intergration method cut by the level set and being on on side of level-set, the oter side, both or only on the levelset itself.
`getfem_level_set_contact.h` and `getfem_level_set_contact.cc`	A level set based large sliding contact algorithm for an easy analysis of implant positioning.
`getfem_convect.h`	Compute the convection of a quantity with respect to a vector field. Used to computate the evolution of a level-set function for instance. Galerkin characteristic method.

Stable.
