| Abstract |
In this talk, we discuss the use of automatic differentiation to
evaluate closure models in large-eddy simulation. We discuss two
approaches to sensitivity analysis (computing derivatives of PDE solutions
to parameters): continuous and discrete. In particular, we discuss the
relationship between these methods and the use of AD in their computation.
We also highlight a number of applications for sensitivity analysis,
namely, their use in optimization, ranking significance of design
variables (of model parameters), and computation of nearby flows.
