Solving Elliptic Equations by Hyperbolic Relaxation — •Hannes Rüter and Bernd Brügmann — Theoretisch-Physikalisches Institut, Friedrich-Schiller-Universität Jena, Deutschland

It will be demonstrated how hyperbolic evolution codes can be used to solve elliptic equations by the hyperbolic relaxation method. We present applications to typical numerical relativity initial data problems, i.e. scalar fields and binary neutron star systems. For the hyperbolic evolution we employ the pseudo-spectral numerical relativity code bamps.
