Defeaturing is a popular CAD/CAE simplification technique that suppresses 'small or irrelevant features' within a CAD model to speed-up downstream processes such as finite element analysis. Unfortunately, defeaturing inevitably leads to analysis errors that are not easily quantifiable within the cur
We analyze two popular classes of a posteriori error estimates within the abstract framework established by Babugka and Aziz (1972). Within this framework, we find that bounds for the a posteriori error estimates depend on several of the same constants as a priori error estimates, notably the famous
