Hi I need to represent fractures in my elastic system. For that I would like to use a discontinuous base (L2_LAGRANGE variable?) and tie overlapping dofs with a penalty function, representing springs (probably weakly).
Is there any example to follow? How can I efficiently find the dofs to tie? I should then use the "add_constraint_row", right? I found another application in the list that uses the "find_nodal_neighbors" function. Is that the right thing to do?
