Residual error based adaptive mesh refinement with the non-intrusive patch algorithm

摘要

AbstractThis paper deals with the introduction of mesh refinement techniques within the non-intrusive patch process. For this, anad hocresidual based explicit error estimator is built, which is adapted to a multi-scale solution, associated with those non-intrusive mesh refinement technique. Moreover, to reduce the global cost of the process, one introduces an estimate of the convergence error of the non-intrusive algorithm, which allows to reduce the number of iterations. This method is discussed and illustrated in various numerical examples.
