Hi,I am just wondering why GTS has been only optional in the past, although the eval functionvoid Function::eval(double* values, const double* x) const http://www.fenics.org/hg/dolfin/file/32bcc3b91dd7/dolfin/function/Function.cpp#l243in the Function class depends on the IntersectionDetector, which in turn depends on GTS.
GTS was added before eval(double* values, const double* x) for finite element functions was added and we haven't bothered reconsidering whether or not GTS should be an optional dependency sicne. Most demos should run without GTS.
Furthermore a 1D function can not evaluated at arbitrary points for functions on 1D grids since the the IntervalCell classhttp://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.
Probably never been tested before. Garth
(Of course the forthcoming CGAL interface will remedy these issues ;)) Greetings, Andre _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@xxxxxxxxxx http://www.fenics.org/mailman/listinfo/dolfin-dev
