* Replace Xt with Xtn when it appears without derivatives.Peter Diener2007-11-12
| | | | | | | | | | Define Xtn[ui] = gtu[uj,uk] Gt[ui,lj,lk] and use it instead of Xt[ui] in all expressions requiring Xt[ui] and not it's derivatives as described in PRD 67 084023 (2003). All RHS still converge for a Schwarzschild black hole in Kerr-Schild coordinates. Signed-off-by: Peter Diener <diener@10-4-34-85.lsu.edu>
* Optimization.Peter Diener2007-11-12
| | | | | | | | | | | | | Added a temporary variable for -D_i D_j alpha + alpha R_ij and it's trace in order to avoid recomputing this when making it trace-free. Also shortened the calculation of the Christoffel symbols from the conformal christoffel symbols. Now they don't involve the derivatives of the determinant of the physical metric, but only derivatives of phi. The number of lines in the RHS calculation went down from 1240 to 1203.

* Fix RHS for gammaPeter Diener2007-11-12
| | | | | | | Implementing the gamma RHS equation (PRD 67 084023 (2003), eqn (26)). The gamma RHS now converges. Signed-off-by: Peter Diener <diener@10-4-34-85.lsu.edu>

| | | | | | | | | | | | | | | | Fixed the calculation of the christoffel symbols in terms of the conformal christoffel symbols. Also fix the calculation of the derivativs of the determinant of the metric. Signed-off-by: Peter Diener <diener@amarok.cct.lsu.edu>

| * Correct errors in equationsErik Schnetter2007-11-07
| | | | | | | | | | | | Correct errors in the symmetrising equations. A factor 1/2 was missing, as pointed out by Peter. The Hamiltonian constraint converges now.
| * Continued development on the BSSN constraintsErik Schnetter2007-11-07
| | | | | | | | | | Rename dtalpha and dtbeta to A and B. Add alternative formulae for the conformal Ricci tensor as comments.
| * Update parameter filesErik Schnetter2007-11-07
