Hi, I am just wondering why GTS has been only optional in the past, although the eval function
void Function::eval(double* values, const double* x) const http://www.fenics.org/hg/dolfin/file/32bcc3b91dd7/dolfin/function/Function.cpp#l243 in the Function class depends on the IntersectionDetector, which in turn depends on GTS. Furthermore a 1D function can not evaluated at arbitrary points for functions on 1D grids since the the IntervalCell class http://www.fenics.org/hg/dolfin/file/32bcc3b91dd7/dolfin/mesh/IntervalCell.cpp#l183 does not provide a implementation. So I wondering how these things work instead? At least I could not find it in the docs and my benchmarks throw an exception when I tried to run the old IntersectionDetector for 1D meshes and points intersection. (Of course the forthcoming CGAL interface will remedy these issues ;)) Greetings, Andre _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@fenics.org http://www.fenics.org/mailman/listinfo/dolfin-dev
