Abstract
In order to generate initial data for nonlinear relativistic simulations, one needs
to solve the Einstein constraints, which can be cast into a coupled set of nonlin-
ear elliptic equations. Here we present an approach for solving these equations on
three-dimensional multi-block domains using finite element methods. We illustrate
