This work compares a numerical and analytical adjoint equation method with respect to boundary condition treatments applied to the quasi‐1D Euler equations. The effect of strong and weak boundary conditions and the effect of flux evaluators on the numerical adjoint solution near the boundaries are discussed. Copyright © 2005 John Wiley & Sons, Ltd.
