msbGrid (multi-structured block Grid) software is a hybrid grid generator, it create differents blocks with structured grid. Each block is connected to its neighbors and those neighboring the domain's boundary are connected to it by a layer of distorted elements (unstructured grid).

This layer can be more or less thin depending on parameters choice like the reference element's size dr, the distance to the boundary wich is controlled by the coefficient d2bC (d2b = dr * d2bC) and the inter-block distance coefficient intbC (intbd = dr * intbC), see Example.

The term reference element refers here to a block's cell (block's finite element). Unlike inter-block's cells wich have different shapes and quality, all block's cells are identical, only the orientation of grid within blocks vary from a block to another..., see Gallery.
