Nettet20. aug. 2024 · Contrary to the previous work , we consider the linearized Navier–Stokes equations and use standard H 1-conforming, piecewise affine, finite element spaces. The key idea is that the ill-posed continuous problem is not regularized. Nettet15. aug. 2015 · The other method uses a second order Taylor expansion to capture the quadratic non-linearities in the Navier–Stokes equations. The benefits of the non-intrusive model reduction approaches presented here are that they do not require any modifications to the source code, due to the fact that they are independent of the …

In this paper we introduce a new preconditioner for linear systems of saddle point type arising from the numerical solution of the Navier–Stokes equations. Our approach is based on a dimensional splitting of the problem along the components of the velocity field, resulting in a convergent fixed-point iteration.
