A geometry repeated on a regular XYZ grid.
The main reason for the introduction of the EGS_XYZRepeater geometry is convenience when defining this type of geometry in an input file, although some optimizations in the implementation of the various geometry methods has also been achieved. A EGS_XYZRepeater is a geometry where a base geometry is repeated times on a regular XYZ grid. It is defined using
:start geometry: library = egs_ndgeometry type = EGS_XYZRepeater repeated geometry = g_name repeat x = xmin xmax Nx repeat y = ymin ymax Ny repeat z = zmin zmax Nz medium = m_name :stop geometry:
where g_name
is the name of a pre-existing geometry. The medium
input is optional. If present, the space within xmin...xmax,ymin...ymax,zmin...zmax
is filled with the nedium named m_name
, otherwise with vacuum. If the repeated geometry has regions, then there will be regions in the geometry, with the space surrounding the repeated geometry having region index . The repeated geometry can be of any type and complexity, the only requirement is that it completely fits within the box about the origin, where =(xmax-xmin)/Nx
, etc.
See repeated_geometry.geom
geometry file for an example of EGS_XYZRepeater use.
A simple example:
:start geometry definition: :start geometry: name = my_sphere library = egs_spheres midpoint = 0 radii = 0.5 :start media input: media = water :stop media input: :stop geometry: :start geometry: name = my_xyz_repeater library = egs_ndgeometry type = EGS_XYZRepeater medium = air repeated geometry = my_sphere # Format is: min, max, N repeat x = -1 4 3 repeat y = -1 4 3 repeat z = -1 4 3 :stop geometry: simulation geometry = my_xyz_repeater :stop geometry definition:
