Modifying the Einstein Equations off the Constraint Hypersuface
J. David Brown, Lisa L. Lowe
A new technique is presented for modifying the Einstein evolution equations off the constraint hypersurface. With this approach the evolution equations for the constraints can be s…
Multigrid elliptic equation solver with adaptive mesh refinement
J. David Brown, Lisa L. Lowe
In this paper we describe in detail the computational algorithm used by our parallel multigrid elliptic equation solver with adaptive mesh refinement. Our code uses truncation erro…
Distorted Black Hole Initial Data Using the Puncture Method
J. David Brown, Lisa L. Lowe
We solve for single distorted black hole initial data using the puncture method, where the Hamiltonian constraint is written as an elliptic equation in R^3 for the nonsingular part…
Dynamical Rotational Instability at Low
Joan M. Centrella, Kimberly C. B. New, Lisa L. Lowe +1
Dynamical instability is shown to occur in differentially rotating polytropes with N = 3.33 and . This instability has a strong m=1 mode, although the m=2, 3, a…
