A natural nonconforming FEM for the Bingham flow problem is quasi-optimal

Abstract

This paper introduces a novel three-field formulation for the Bingham flow problem and the relative named after Mosolov and low-order discretizations: a nonconforming for the classical formulation and a mixed finite element method for the three-field model. The two discretizations are equivalent and quasi-optimal in the sense that the H1 error of the primal… (More)
