Detailed Description

Construct a general CSG universe, aka a "unit".

A "unit" is a region of space (specified by the "boundary" object) that is divided up into multiple smaller regions:

A "material" (aka "media" in SCALE) is a single homogeneous CSG object filled with a particular material ID. This is equivalent to a leaf "physical volume" in a GDML/Geant4 volume hierarchy.
A "daughter" (aka "hole" in SCALE) is another unit that is transformed and placed into this universe.

Regarding boundary conditions: "Input" is for how the unit is defined:

========== ========================================================== Input Description ========== ========================================================== Implicit Boundary implicitly truncates interior (KENO) Explicit Interior CSG definition includes boundary (RTK) ========== ==========================================================

Additionally, whether the universe is the top-level global universe (see the ExteriorBoundary type) affects the construction.

========== ========================================================== ExtBound Description ========== ========================================================== Daughter Boundary is already truncated by higher-level unit Global Boundary must explicitly be represented as a volume ========== ==========================================================

These result in different z ordering for the exterior:

===== ===== ================== ======================================== Inp ExB Resulting zorder Description ===== ===== ================== ======================================== I N implicit_exterior Higher-level universe truncates X N implicit_exterior Higher-level universe truncates I Y exterior Global unit that truncates other regions X Y media Global unit with well-connected exterior ===== ===== ================== ========================================

Member Function Documentation

◆ build() [1/2]

void celeritas::orangeinp::UnitProto::build ( ProtoBuilder & input ) const

finalvirtual

Construct a universe input from this object.

Construction is done from highest masking precedence to lowest (reverse zorder): exterior, then holes, then arrays, then media.

Todo:: "simple safety" flag is set inside "unit inserter": move here once we stop importing from SCALE via OrangeInput.

Todo:: The nearest internal surface is probably not the safety distance, but it's better than nothing

Todo:: Save material IDs as well

Implements celeritas::orangeinp::ProtoInterface.

◆ build() [2/2]

auto celeritas::orangeinp::UnitProto::build	(	Tol const &	tol,
		BBox const &	bbox
	)		const

Construct a standalone unit for testing or external interface.

The universe ID in the resulting "fill" is the index into the input daughters list, which is the same ordering as the array of this->daughters().

The "exterior boundary" argument determines whether the outer boundary needs to be deleted (assumed inside, implicit from the parent universe's boundary) or preserved.

Todo:: We can sometimes eliminate CSG surfaces and nodes that aren't used by the actual volumes>
