 The Augmented Lagrangian method is used to iterate several times over a single time step, to correct contact forces (augmentation) to get a gap $g$ smaller than a given tolerance (defined by the parameters ''PRECONNORMALGAP'' and ''PRECONTANGENTGAP'' of the ''[[doc:user:elements:contact:elements|ElementProperties]]''). Contact forces at the iteration $i$ are written : The Augmented Lagrangian method is used to iterate several times over a single time step, to correct contact forces (augmentation) to get a gap $g$ smaller than a given tolerance (defined by the parameters ''PRECONNORMALGAP'' and ''PRECONTANGENTGAP'' of the ''[[doc:user:elements:contact:elements|ElementProperties]]'').
