Title:
Stabilization of Discrete Adjoints by error attenuation

Abstract:

The Reverse Accumulation method for solving Discrete Adjoint problems often times requires the solution of a linear fixed point equation. If some of the components in this iteration are unstable, different stabilization techniques can be applied. In this talk we discuss how some of these implementations can be seen as a special kind of error attenuation.
