A comparison of momentum transport models for numerical relativity
Matthew D. Duez, Alexander Knight, Francois Foucart +6
The main problems of nonvacuum numerical relativity, compact binary mergers and stellar collapse, involve hydromagnetic instabilities and turbulent flows, so that kinetic energy at…

Axisymmetric Hydrodynamics in Numerical Relativity Using a Multipatch Method
Jerred Jesse, Matthew D. Duez, Francois Foucart +7
We describe a method of implementing the axisymmetric evolution of general-relativistic hydrodynamics and magnetohydrodynamics through modification of a multipatch grid scheme. In…
