/solver/augmented_lagrangian (object)

/solver/augmented_lagrangian

Description

Parameters for the AL for imposing Dirichlet BCs. If the bc are not imposable, we add wubc2 to the energy (u is the solution at the Dirichlet nodes and bc are the Dirichlet values). After convergence, we try to impose bc again. The algorithm computes E + a/2*AL^2 - lambda AL, where E is the current energy (elastic, inertia, contact, etc.) and AL is the augmented Lagrangian energy. a starts at initial_weight and, in case DBC cannot be imposed, we update a as a *= scaling until max_weight.
