HexagonalGridDivision
Divide the mesh along a hexagonal grid. Numbering of pin divisions increases first counterclockwise, then expanding outwards from the inner ring, then axially. Inner-numbering is within a radial ring, outer-numbering is axial divisions
Points that lie outside the hexagonal grid may be assigned to the grid outer bins using the "assign_domain_outside_grid_to_border" parameter. This is the current treatment for background/duct regions around hexagonal pins in an assembly.
Using a Positions object as the "center_positions" parameter, multiple hexagonal 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 hexagonal grid, based on the number of rings and axial discretization specified.
For points lying within the standard tolerance of an internal boundary of the hexagonal 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.
