CartesianGridDivision

Divide the mesh along a Cartesian grid. Numbering increases from bottom to top and from left to right and from back to front. The inner ordering is X, then Y, then Z

The number of mesh divisions/regions is the product of the number of bins in each direction.

Points that lie outside the Cartesian grid may be assigned to the grid outer bins using the "assign_domain_outside_grid_to_border" parameter.

Using a Positions object as the "center_positions" parameter, multiple Cartesian grids can be created around each position computed by that object. The division index of a point is then:

with the index in the Positions object of the position nearest from the point and the number of divisions for a single Cartesian grid, based on the X/Y/Z discretization specified.

commentnote

For points lying within the standard tolerance of an internal boundary of the Cartesian grid, this object will output a warning. If you do not mind the indetermination on which bins they belong to but do mind that a warning is output, please reach out to a MOOSE (or any MOOSE app) developer.
