From 7738ae27379fd4aee0124bd3b224295fcaf5cfce Mon Sep 17 00:00:00 2001 From: jthorn Date: Sun, 6 Oct 2002 14:33:00 +0000 Subject: // The first time we (try to) find a given horizon, our initial // guess is likely to be rather inaccurate, so we may need a // larger number of iterations. But if we've found this horizon // before, then we have its previous position as an initial guess, // so we shouldn't need as many iterations. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@795 f88db872-0e4f-0410-b76b-b9085cfa78c5 --- src/driver/initial_guess.cc | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'src/driver/initial_guess.cc') diff --git a/src/driver/initial_guess.cc b/src/driver/initial_guess.cc index 2f55312..41961cc 100644 --- a/src/driver/initial_guess.cc +++ b/src/driver/initial_guess.cc @@ -279,7 +279,11 @@ if (print_msg_flag) " expected exactly one r>0 solution to quadratic, got 0 or 2!\n" " %s patch (irho,isigma)=(%d,%d) ==> (rho,sigma)=(%g,%g)\n" " direction cosines (xcos,ycos,zcos)=(%g,%g,%g)\n" -" ==> r_plus=%g r_minus=%g\n" +" r_plus=%g r_minus=%g\n" +" ==> this probably means the initial guess surface doesn't contain\n" +" the local origin point, or more generally that the initial\n" +" guess surface isn't a Strahlkoerper (\"star-shaped region\")\n" +" with respect to the local origin point\n" , p.name(), irho, isigma, double(rho), double(sigma), -- cgit v1.2.3
