Excising das All: Evolving Maxwell waves beyond scri (2006)
Misner, Charles W., Van Meter, James R., Fiske, David R.
We study the numerical propagation of waves through future null infinity in a conformally compactified spacetime. We introduce an artificial cosmological constant, which allows us some control over...

Wave zone extraction of gravitational radiation in three-dimensional numerical relativity (2005)
Fiske, David R., Baker, John G., Van Meter, James R., Choi, Dae-Il, Centrella, Joan M.
We present convergent gravitational waveforms extracted from three-dimensional, numerical simulations in the wave zone and with causally disconnected boundaries. These waveforms last for multiple...
Computing spherical harmonic decompositions is a ubiquitous technique that arises in a wide variety of disciplines and a large number of scientific codes. Because spherical harmonics are defined by...
Evolving a puncture black hole with fixed mesh refinement (2004)
Imbiriba, Breno, Baker, John, Choi, Dae-Il, Centrella, Joan, Fiske, David R., Brown, J. David, ...
We present an algorithm for treating mesh refinement interfaces in numerical relativity. We detail the behavior of the solution near such interfaces located in the strong field regions of dynamical...
Toward standard testbeds for numerical relativity (2004)
Alcubierre, Miguel, Allen, Gabrielle, Bona, Carles, Fiske, David R., Goodale, Tom, Guzman, F. Siddhartha, ...
In recent years, many different numerical evolution schemes for Einstein's equations have been proposed to address stability and accuracy problems that have plagued the numerical relativity community...

Numerical studies of constraints and gravitational wave extraction in general relativity (2004)
Thesis (Ph. D.) -- University of Maryland, College Park, 2004.
Toward Making the Constraint Hypersurface an Attractor in Free Evolution (2003)
There is an abundance of empirical evidence in the numerical relativity literature that the form in which the Einstein evolution equations are written plays a significant role in the lifetime of...
