Analysis of Velocity-Flux Least-Squares Principles for the Navier--Stokes Equations: Part II

Abstract

This paper continues the development of the least-squares methodology for the solution of the incompressible Navier--Stokes equations started in Part I. Here we again use a velocity-flux first-order Navier--Stokes system, but our focus now is on a practical algorithm based on a discrete negative norm.
