Understanding the behavior of fluids requires solving the Navier–Stokes equation (NSE). However, the NSE is a complex partial differential equation that can be challenging to solve, and classical numerical methods can be computationally expensive. In this paper, we propose enhancing physics‐informed...
ing Spalart-Allmaras one-equation model implemented by Frink. 12 Governing Equations The integral form of the Navier-Stokes equations, which govern the compressible, Newtonian flow of fluid in the absence of external forces, can be written as ∂ ∂t QdV + F(Q) · ˆ ndS = G(Q...

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...
In this paper, physics-informed neural network (PINN) based on characteristic-based split (CBS) is proposed, which can be used to solve the time-dependent Navier-Stokes equations (N-S equations). In this method, The output parameters and corresponding losses are separated, so the weights betwe...
