Numerical solution of the obstacle problem by the penalty method

The penalty method is used to compute approximations of the solution of the obstacle problem. By coupling the penalty parameter ε and the discretization parameterh quasi-optimal error estimates in the energy-norm are derived.ZusammenfassungDie Penalty-Methode wird benutzt, um Approximationen für die Lösung des Hindernis-Problems zu berechnen. Durch Kopplung des Penalty-Parameters ε und des Diskretisierungs-Parametersh werden quasi-optimale Fehlerabschätzungen in der Energie-Norm hergeleitet.
