Boundaryfitted
Boundaryfitted refers to coordinate systems or grids that conform to the boundaries of a physical domain. In numerical simulation, boundaryfitted grids map a complex, possibly curved boundary in physical space to a simpler computational space, typically a rectangle or box, allowing accurate boundary condition specification and improved resolution near walls or interfaces.
The technique is common in finite difference and finite element methods. It uses curvilinear coordinates (xi,
Applications span computational fluid dynamics, heat and mass transfer, electromagnetics, groundwater flow, and structural analysis, particularly
Advantages include faithful boundary representation, easier imposition of Dirichlet and Neumann conditions, and improved accuracy near
