Ants developer manual

Geometry and indexing

Ants calculation mesh is determined by input cards

• (core width_x, core width_y) or (core width_xy), core axial_nodes, core axial_heights, division_x, division_y, division_z, core columns, core rows, and fuel load for rectangular geometry
• core width_xy, core axial_nodes, core axial_heights, division_z, core columns, core rows, and fuel load for hexagonal geometry
• core width_xy, core axial_nodes, core axial_heights, division_hex, division_z, core columns, core rows, and fuel load for triangular geometry

Number of input nodes is determined by core axial_nodes, core columns, core rows and fuel load. The sizes of input nodes are determined by core width_x, core width_y, core width_xy and core axial_heights. The number and sizes of the calculation nodes can be changed using division_x, division_y, division_hex and division_z.
