Yanlai Chen, University of Massachusetts at DartmouthYanlai Chen, University of Massachusetts at DartmouthEwing 336Title: <br> Reduced Basis Method: Applications, recent improvements on efficiency and robustness, and a new iterative scheme Abstract:<br> Models of reduced computational complexity is indispensable in scenarios where a large number of numerical solutions to a parametrized problem are desired in a fast/real-time fashion. Thanks to an offline-online procedure and the recognition that the parameter-induced solution manifolds can be well approximated by finite-dimensional spaces, reduced basis method (RBM) and reduced collocation method (RCM) can improve efficiency by several orders of magnitudes. The accuracy of the RBM/RCM solutions is maintained through a rigorous a posteriori error estimator whose efficient and accurate evaluation is critical. After a brief introduction of the RBM, this talk will show our recent work on novel approaches for speeding up the offline portion of the approaches by around 6-fold, and new residual-based and residual-free strategies for circumventing error stagnation that is traditional of the classical RBM. If time permits, we will introduce a new iterative scheme inspired by RBM that outperforms conjugate gradient method with multigrid as a preconditioner for linear systems discretizing Poisson's equation. 4/12/2018 3:00:00 PM4/12/2018 4:00:00 PMFalse
