bim-solver

Bimetric 3+1 Toolkit implements the standard 3+1 evolution and the covariant BSSN evolution schemes for spherically symmetric bimetric and GR spacetimes.

The project goal is the construction of a computational toolkit for the evolution of 3+1 equations of modified theories of gravity in spherical symmetry, at the same time resembling the functionality of the EinsteinToolkit to ease transition to the full scale projects. The current implementation handles bimetric and GR spacetimes.

Note that the toolkit can handle any system of differential equations. For a pedagogical example how to use the toolkit, see Gowdy spacetimes solver.
