Detailed Description

A single block x-y-z rectilinear mesh addressable as i,j,k with simplified creation. Some of the input is similar to blockMeshDict, but since this specialization is for a single-block that is aligned with the x-y-z directions, it provides a different means of specifying the mesh.

Dictionary controls

Property	Description	Required	Default
`x`	X-direction grid specification	yes
`y`	Y-direction grid specification	yes
`z`	Z-direction grid specification	yes
`scale`	Point scaling	no	1.0
`expansion`	Type of expansion (ratio/relative)	no	ratio
`boundary`	Boundary patches	yes
`defaultPatch`	Default patch specification	no

Grid coordinate controls

Property	Description	Required
`points`	Locations defining the mesh segment	yes
`nCells`	Divisions per mesh segment	yes
`ratios`	Expansion values per segment	no

A negative expansion value is trapped and treated as its reciprocal. by default, the expansion is as per blockMesh and represents the ratio of end-size / start-size for the section. Alternatively, the relative size can be given.
