Geometry aware physics informed neural network surrogate for solving Navier–Stokes equation (GAPINN)
Advanced Modeling and Simulation in Engineering Sciences, 2022 Many real world problems involve fluid flow phenomena, typically be described by the Navier–Stokes equations. The Navier–Stokes equations are partial differential equations (PDEs) with highly nonlinear properties. Currently mostly used methods solve this
