Detailed Description

Control error in the 3D Rotation coordinate map.

Details

Computes the error in the angle rotated by the system using a slightly modified version of Eq. (41) from [149]. The equation is

δq=C×XCX

where X=xAxB and C=cAcB. Here, object A is located on the positive x-axis and object B is located on the negative x-axis, X is the difference in positions of the centers of the mapped objects, and C is the difference of the centers of the excision spheres, all in the grid frame.

Requirements:

  • This control error 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 Rotation control system
