 Nicolson–Ross–Weir method

The Nicolson–Ross–Weir (NRW) method is a numerical technique used primarily in computational fluid dynamics and heat transfer to solve the unsteady-state heat conduction equations, particularly within a finite difference framework. It is a finite difference method that is particularly suited for solving parabolic partial differential equations. **Key Features of the Nicolson–Ross–Weir Method:** 1.
