A successive constraint method with minimal offline constraints for lower bounds of parametric coercivity constant
Résumé
A posteriori error estimates are a key ingredient for the certified reduced basis method. Sharp error bounds rely on the construction of lower bounds for the coercivity or inf-sup stability constant. The Successive Constraint Method (SCM) has been previously proposed to compute such lower bounds, using an efficient Offline-Online strategy. We present in this article some modifications to the SCM to get rid of user-dependent parameters, which also improve convergence and reduce the computational cost of the method.
