A Three-Dimensional Hydrodynamics Code for Modeling Sources of Gravitational Radiation
We have developed a 3-D Eulerian hydrodynamics code to model sources of gravitational radiation. The code is written in cylindrical coordinates $(\varpi,z,φ)$ and has moving grids in the $\varpi$ and $z$-directions. We use Newtonian gravity and calculate the gravitational radiation in the quadrupole approximation. This code has been tested on a variety of problems to verify its accuracy and stability, and the results of these tests are reported here.
