Constraint-preserving Sommerfeld conditions for the harmonic Einstein equations
2007 (English)In: PHYSICAL REVIEW D, ISSN 1550-7998, Vol. 75, no 4, 044002- p.Article in journal (Refereed) Published
The principle part of Einstein equations in the harmonic gauge consists of a constrained system of 10 curved space wave equations for the components of the space-time metric. A new formulation of constraint-preserving boundary conditions of the Sommerfeld-type for such systems has recently been proposed. We implement these boundary conditions in a nonlinear 3D evolution code and test their accuracy.
