structured grid

structured grid

[¦strək·chərd ′grid]
(mathematics)
In the discretization of partial differential equations, an organized set of points formed by the intersections of the lines of a boundary-conforming curvilinear coordinate system, at which the equations are expressed in discrete form.

First, to perform the grid resolution (numerical factor) effect study that was previously described, we used the computational domain shown in Figure 1 with six uniform structured grid sizes (see Figure 2).
Structured grid is also known as FDM [6, 7] grid, that is difference grid, unstructured grid FEM mesh is also known that the finite element mesh.
In the solver package, the solution of the Reynolds Averaged Navier-Stokes Equations is obtained by using finite volume method with a body-fitted structured grid. A cell-centered layout is employed in which the pressure, turbulence and velocity unknowns share the same location.
The first test problem is the 3D 7-point Laplacian on a structured grid:
In the case of JS Bach, at least, you can expect compositions that rise through the mathematically structured grid of point-counterpoint to arrive at something that is, even for many atheists of contemporary chamber music, "sublime."
Around each 2D section, a structured grid made of 101075 quadrilateral cells has been constructed (average cell count; exact number depends on the 2D section).
However, some of the fastest and most accurate CFD codes can be difficult to apply to complicated geometry because they require a highly structured grid of cells.
Engineers used a preprocessor to generate a 3-D multiple block and structured grid of the complex scroll geometry, and used computational fluid dynamics software to model flow around the exterior and through the interior of the scroll.
