Multiblock

Multiblock is a term used for a structure assembled from several smaller blocks that together form a single functional unit. It emphasizes modularity and the ability to change, upgrade, or replace individual blocks without rebuilding the whole system. Blocks usually include standardized interfaces for mechanical alignment, as well as connections for electrical, fluid, or data links to allow seamless operation across boundaries.

In engineering and construction, multiblock concepts appear in modular construction and prefab machinery. Standard blocks or panels are manufactured off-site and assembled on-site, enabling faster deployment and easier maintenance. Key challenges include precise alignment, reliable transfer of loads and services between blocks, and ensuring consistent quality and safety across modules.

In computational methods, multiblock grids partition a complex domain into multiple block-structured meshes that interface at block boundaries. This approach supports handling intricate geometries and localized refinement while keeping grid generation manageable and solver performance high.

In gaming and simulation, multiblock structures are common in sandbox environments, where players arrange blocks to form machines or reactors that operate when properly configured according to game rules.
