Hi Chen, No and yes - the same functionality has been moved into the Manifold classes, which are much more general than the old Boundary classes. For example, GridGenerator::hyper_ball automatically attaches a SphericalManifold to the boundary of the input Triangulation, which achieves the same result as attaching a HyperBallBoundary.
More information is available at the module page: https://www.dealii.org/current/doxygen/deal.II/group__manifold.html Do you need to do anything more complex than generate a spherical geometry? If not, using SphericalManifold in place of HyperBallBoundary should do most of what you need to do (though, again, this is now done automatically by the grid generator functions).

In dealii-9.2.0, is there anyway to use some functions to realize the same function like the following codes which must include <deal.II/grid/tria_boundary_lib.h> and will work in dealii-9.0.0? static const HyperBallBoundary<dim> boundary(p,radius); triangulation.set_boundary (80, boundary); Best, Chen -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
