Sensitivity Analysis for Navier-Stokes Equations on Unstructured Meshes Using Complex Variables
TL;DR: Although a step size parameter is required, the numerical derivatives are not subject to subtractive cancellation errors and, therefore, exhibit true second-order accuracy as the step size is reduced, in contrast to the use of finite differences.
