Mixed-hybrid methods for the analysis of potential flow
Abstract
Compared to conventional methods, mixed-hybrid finite element methods have the advantage of weaker continuity requirements on base functions, but also the drawback of delicate convergence properties. In the present analysis of two important classes of mixed-hybrid finite elements, particularly well suited for analyzing flow problems, emphasis is placed on questions of accuracy and numerical stability, as well as on the derivation of criteria for selecting appropriate basis functions that guarantee convergence. The analysis is carried out for the problem of determining stream lines.
