Hi Hubert!
Thanks. It seems that the option which you are sending is for the
overall libMesh compilation (correct me if I'm wrong). I am interested
in having my libMesh with the ability to process complex numbers, and
just compiling a specific program (not the whole libMesh) without
complex numbers. Do you know if there is a way for that? Thank you
again.
The decision to use complex numbers is a compile-time one. If your
program
links against a libmesh with complex numbers enabled, then the Number
type
is #defined to be std::complex<double>. Furthermore certain libmesh
templates, in particular the NumericVector and SparseMatrix classes are
only instantiated for type Number, so these will all use
std::complex<double> internally in such builds.
Thank you very much, John. Indeed, my suspicion was in the right track
(see previous e-mail where I answer to Hubert and Paul). If I may add to
your comment in a joyous way: ...and if you try to modify the
LIBMESH_USE_COMPLEX_NUMBERS=0, it will die a terrible death :P .
