This work is concerned with the development of computational methods for

approximating sensitivities of solutions to boundary value problems.

We focus on the continuous sensitivity equation method and

investigate the application of adaptive meshing and smoothing

projection techniques to enhance the basic scheme. The fundamental

ideas are first developed for a one dimensional problem and then

extended to 2-D flow problems governed by the incompressible

Navier-Stokes equations. Numerical experiments are conducted to test the

algorithms and to investigate the benefits of adaptivity and smoothing.
