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 intergation 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. |
