Cactus Code Thorn Maximal Authors : ... Managed by : ... <...@...........> Version : ... CVS info : $Header$ -------------------------------------------------------------------------- 1. Purpose of the thorn This thorn setus up the maximal slicing equation (dtrK/dt=0): __2 ij i \/ alpha = alpha K K + beta d trK + matter terms ij i The laplacian operator is the full non-linear one, but it most be supplied by the elliptic solver. This thorn only fills in the right hand side of the equation and then calls an elliptic solver. The equation is rewritten as: __2 \/ alpha + M alpha = N and the thorn fills in the values of M and N. Notice that if K=0, then we can safely set N=0 from the equation above. This is normally assumed to be true unless otherwise specified. 2. Dependencies of the thorn This thorn additionally requires thorns: einstein ellbase 3. Thorn distribution This thorn is available to anyone.
