Zusammenfassung
This work describes a Finite Element Newton Method for the solution of the stationary
Navier–Stokes equations for two-dimensional incompressible flows. We start from the weak
variational formulation of the problem and adopt an unequal order interpolation
\$P^1\$–\$P^2\$ for pressure and velocity. Rather general boundary conditions are considered. The Newton
method for the nonlinear system of coupled equations is written in a particularly
transparent incremental form and the Jacobian linear system is solved by means of a dire
ct algorithm (MUMPS). The results of some numerical tests are provided to demonstrate the correctness and capability of the method.
