Rio: A new computational framework for accurate initial data of binary black holes

Understand

We present a computational framework (Rio) in the ADM 3+1 approach for numerical relativity.

• This work enables us to carry out high resolution calculations for initial data of two arbitrary black holes.
• We use the transverse conformal treatment, the Bowen-York and the puncture methods.
• For the numerical solution of the Hamiltonian constraint we use the domain decomposition and the spectral decomposition of Galerkin-Collocation.
