boxstructured
Boxstructured is a term used in computational methods to describe a grid or mesh arrangement in which a domain is subdivided into a regular, axis-aligned array of boxes (rectangular prisms in 3D). Each box has a uniform size and neighbors are arranged in a predictable, grid-like topology. This contrasts with unstructured meshes where cells may have arbitrary shapes and connectivity.
Box-structured grids are common in finite difference and finite volume solvers because they enable simple indexing,
Block-structured or box-structured grids extend the idea by partitioning the domain into several non-overlapping blocks that
Advantages of boxstructured grids include simplicity, speed, and ease of boundary condition implementation. Limitations involve difficulty
Boxstructured grids are used across fields such as computational fluid dynamics, heat transfer, groundwater modeling, volume
