Sensitivity analysis on chaotic dynamical systems by Finite Difference Non-Intrusive Least Squares Shadowing (FD-NILSS)
Angxiu Ni, Qiqi Wang, Pablo Fernandez +1
We present the Finite Difference Non-Intrusive Least Squares Shadowing (FD-NILSS) algorithm for computing sensitivities of long-time averaged quantities in chaotic dynamical system…
Multiple Shooting Shadowing for Sensitivity Analysis of Chaotic Dynamical Systems
Patrick J. Blonigan, Qiqi Wang
Sensitivity analysis methods are important tools for research and design with simulations. Many important simulations exhibit chaotic dynamics, including scale-resolving turbulent…
Toward a chaotic adjoint for LES
Patrick J. Blonigan, Pablo Fernandez, Scott M. Murman +3
Adjoint-based sensitivity analysis methods are powerful tools for engineers who use flow simulations for design. However, the conventional adjoint method breaks down for scale-reso…
