We demonstrate a simple example about how to design my own algorithm for Navier-Stokes equation by weak form PDE and LiveLink™ for MATLAB®. After the computation, we get the same solution as other FEM packages (FreeFEM++ & FeniCs) at each iterative step, and we can see the Navier...
due to the typical conciseness of the Matlab coding language,could allow for fast and effective implementation of new models or algorithms.Innovative numerical methods are discussed in the paper.The pressure equation is derived with a quasi-segregation technique leading to an iterative scheme obtained ...

We present a Reduced Order Model (ROM) which exploits recent developments in Physics Informed Neural Networks (PINNs) for solving inverse problems for the Navier–Stokes equations (NSE). In the proposed approach, the presence of simulated data for the fl
(x) Poisson equation in 2D. Steps 11–12 solve the Navier-Stokes equation in 2D: (xi) cavity flow; (xii) channel flow. Students are instructed to follow these steps one by one, without skipping any! The most important step is #1, in fact. Everything builds from there. ...
Throughout this paper we will use the corner singularity functions for the Stokes operator L[v,q]=[−μΔv+∇q,−divv] with no-slip boundary condition (see [2, Section 5.1]). The leading singular eigenvalues λi, which are the roots of the trigonometric equation: sin2(λω)−...
