Most of the physical laws that govern the dynamics of a system can be described by partial differential equations. For example, the Navier–Stokes equations are a set of partial differential equations derived from the conservation laws (i.e., conservation of mass, momentum, and energy) that govern fluid mechanics. The solution of the Navier–Stokes equations with appropriate initial and boundary conditions allows the quantification of flow dynamics in a precisely defined geom… Webb12 apr. 2024 · In TPINN, one or more layers of physics informed neural network (PINN) corresponding to each non-overlapping subdomains are changed using a unique set of …
