75 : *
76 : * \brief A general domain for two compact objects.
77 : *
78 : * \image html binary_compact_object_domain.png "A BHNS domain."
79 : *
80 : * Creates a 3D Domain that represents a binary compact object solution. The
81 : * Domain consists of 4 or 5 nested layers of blocks; these layers are, working
82 : * from the interior toward the exterior:
83 : *
84 : * - **Object A/B interior**: (optional) The block at the center of each
85 : * compact object, if not excised. If present, this block is a cube. If
86 : * excised, the hole left by its absence is spherical.
87 : * - **Object A/B shell**: The 6 blocks that resolve each individual compact
88 : * object. This layer has a spherical outer boundary - if the corresponding
89 : * interior block exists, then the layer is a cube-to-sphere transition; if
90 : * the interior block is excised, then the layer is a spherical shell.
91 : * - **Object A/B cube**: The 6 blocks that surround each object with a cube.
92 : * Around each compact object, this layer transitions from a sphere to a cube.
93 : * - **Envelope**: The 10 blocks that transition from the two inner cubes to a
94 : * sphere centered at the origin.
95 : * - **Outer shell**: The 10 blocks that form an outer shell centered at the
96 : * origin, consisting of 2 endcap Wedges on the +x and -x axes, and 8 half
97 : * Wedges along the yz plane. This layer is spherical, so a logarithmic map
98 : * can optionally be used in this layer. This allows the domain to extend to
99 : * large radial distances from the compact objects. This layer can be
100 : * h-refined radially, creating a layer of multiple concentric spherical
101 : * shells.
102 : *
103 : * \par Notes:
104 : * - Object A is located to the right of the origin (along the positive x-axis)
105 : * and Object B is located to the left of the origin in the Grid frame.
106 : * - This domain offers some grid anchors. See
107 : * `domain::creators::bco::create_grid_anchors` for which ones are offered.
108 : * - "Cutting plane" refers to the plane along which the domain divides into two
109 : * hemispheres. The cutting plane always intersects the x-axis at the origin.
110 : * - The x-coordinate locations of the two objects should be chosen such that
111 : * the center of mass is located at x=0 at the initial time (typically t=0).
112 : * - The cubes are first constructed at the origin. Then, they are translated
113 : * left/right by their Object's x-coordinate and offset depending on the cube
114 : * length.
115 : * - The CubeScale option describes how to scale the length of the cube
116 : * surrounding object A/B. It must be greater than or equal to 1.0 with 1.0
117 : * meaning the side length of the cube is the initial physical separation
118 : * between the two objects. If CubeScale is greater than 1.0, the centers of
119 : * the two objects will be offset relative to the centers of the cubes.
120 : * - Alternatively, one can replace the inner shell and cube blocks of each
121 : * object with a single cartesian cube. This is less efficient, but allows
122 : * testing of methods only coded on cartesian grids.
123 : *
124 : * \par Time dependence:
125 : * The following time-dependent maps are applied:
126 : *
127 : * - A piecewise `Expansion`, a `Rotation` and a piecewise `Translation` is
128 : * applied to all blocks from the Grid to the Inertial frame. However, if there
129 : * is a shape map in the block (defined below), then the expansion, rotation,
130 : * and translation maps go from the Distorted to the Inertial frame.
131 : * - If an object is excised, then the corresponding shell has a
132 : * `Shape` map. The shape map goes from the Grid to the Distorted frame.
133 : *
134 : * All time dependent maps are optional to specify. To include a map, specify
135 : * its options. Otherwise specify `None` for that map. You can also turn off
136 : * time dependent maps all together by specifying `None` for the
137 : * `TimeDependentMaps` option. See
138 : * `domain::creators::bco::TimeDependentMapOptions`. This class must pass a
139 : * template parameter of `false` to
140 : * `domain::creators::bco::TimeDependentMapOptions`.
141 : *
142 : * The wavezone can support using spherical harmonic shells by setting
143 : * `SphericalHarmonicsInWavezone` to `true`. In this case you cannot set an
144 : * angular h-refinement level in the angular directions, and you can only choose
145 : * the \f$\ell\f$ of the shells since having an \f$m_{\max}\f$ below the maximum
146 : * allowed from the \f$\ell\f$ can drive simulations unstable.
147 : *
148 : * The `UseWorldtube` option defaults to `false`. When set to `true`, some of
149 : * the functions of time will be `IntegratedFunctionOfTime` used to control the
150 : * orbit of the worldtube.
