For future reference, if you are in doubt on how to use a single
class/function, you can skim through the directory tests, i.e.,
tests/manifold/composition_manifold_*
would have shown to you an example which is identical to what you are trying to
achieve, and in general it contains very simple pieces of codes that run very
simple tests and show how to use almost every single class/function of the
deal.II library.
This should be your second step, though, after reading carefully the
documentation. ;)
If you think there are things that should be changed in the documentation to
make the CompositionManifold class clearer (a very young class indeed), please
feel free to make a pull request. We’d be happy to include your comments in the
library!
