I present results on the encounter of two black holes that are initially on a hyperbolic-like orbit simulated with the numerical relativity code SpEC. I discuss the dynamical capture scenario as well as the scattering scenario, in which the black holes remain unbound during the encounter. In dynamical captures, the binary becomes bound due to the emission of gravitational waves, which poses a possible formation scenario of highly eccentric binary mergers. I present and discuss waveforms for both scenarios and analyse the dynamics of in scattering encounters in terms of the scattering angle.
