We discuss the impact of time integration and adaptation, and the relation with structure preservation. We illustrate our findings through two distinct classes of problems: fluid structure interaction in the laminar regime, and compressible flows at low\/moderate Mach number. Numerical results clearly show that the preservation of the divergence-free constraint for incompressible flows enhances the long-time stability of reduced-order models, and model reduction alleviates the underlying stiffness of the high-fidelity model, and ultimately enables significantly larger time steps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tommaso Taddei Sapienza University of Rome &#8211; \ud83c\uddee\ud83c\uddf9 Rome (Italy) Projection-based model reduction of evolutionary problems: structure preservation and adaptive time stepping This talk addresses recent developments of projection-based model reduction for parametric evolutionary problems with emphasis on computational fluid dynamics (CFD) problems.
