Motion4D - A library for lightrays and timelike worldlines in the theory of relativityThomas Müller, Frank GraveThe Motion4D-library solves the geodesic equation as well as the parallel- and Fermi-Walker-transport in four-dimensional spacetimes numerically. Initial conditions are given with respect to natural local tetrads which are adapted to the symmetries or the coordinates of the spacetime. Beside some already implemented metrics like the Schwarzschild and Kerr metric, the object oriented structure of the library permits to implement other metrics or integrators in a straight forward manner.
Catalogue Identifier: AEEX_v1_0 The code documentation generated by doxygen can be found here. Implemented metrics:
The expected results are:
