Description
I will describe SPHINCS-BSSN: a code that combines spacetime evolution on a grid with a Lagrangian treatment of the matter. That is, the matter is evolved using the method of Smoothed Particle Hydrodynamics (SPH). I will describe the advantages (and disadvantages) of using particle methods and will describe how we overcame the technical challenges of coupling the matter to the spacetime. I will finally present some basic tests of the code as well as some new results.
