build a level set function on mesh with zero on the boundary.
Solves Laplace equation with zero Dirichlet on the boundary. Used to create simple level sets for contact testing
Definition at line 72 of file getfem_level_set_contact.h.
| bgeot::pgeometric_trans level_set_contact::face_trans_of_elem | ( | bgeot::pgeometric_trans | pelem_trans | ) |
Determines geometric transformation on the face of the element based on the geometric transformation of the element itself.
Works only for PK and QK elements

| ) |
adding level set based normal contact brick to the model.
The contact is etablished between the
| mcb | - master contact body and |
| scb | - slave contact body, defined on |
| md | - model object |
| rg | - optional assumed contact region helping to narrow down contact search Note, this contact algorithm is note stabilized, hence, master contact body mesh should be coarser than slave's mesh. Otherwise this contact constraint will violate inf-sub condition and the solver will fail (or diverge, if it's iterative) |

| ) |
Solves a model that has contact in it.
Function checks wheather the contact area has converged
| sf | - a pointer to a newton solver function, can be, for instance, getfem::standard_solve |
| it_newton | - iteration object for newton method |
| it_staggered | - iteration object for staggered calculation between conact detection and newton method (only max num. of iterations should be provided) |
| lsolver | - solver for a linear system |
| ls | - reference to line search method |
