Detailed Description

template<size_t DerivOrder, typename Measurement>
struct control_system::Systems::Expansion< DerivOrder, Measurement >

Controls the 3D CubicScale map.

Details

Controls the function \(a(t)\) (a FunctionOfTime) in the CubicScale coordinate map, while the function \(b(t)\) is typically an analytic function (usually a FixedSpeedCubic). See CubicScale for definitions of both \(a(t)\) and \(b(t)\).

Requirements:

  • This control system requires that there be exactly two objects in the simulation
  • Currently both these objects must be black holes
  • Currently this control system can only be used with the BothHorizons measurement
  • Currently this control system can only be used with the Expansion control error
