Thank you for the kind answer and for the really useful references. I have tried to obtain a triangulation on a domain for which the bottom boundary is a bump described by a sinusoidal function. Following the simplest examples with strings, I have defined a FunctionManifold instance with

Giuseppe, Searching for FunctionMnaifold in the tests folder should give you a couple of examples on how to use FunctionManifold with an analytical function. Most of them use std::strings but tests/fe/fe_values_function_manifold.cc and tests/mappings/mapping_q_manifold_02.cc actually use Function

[deal.II] FunctionManifold class

2022-01-30 Thread giuseppe orlando
Good morning everyone, I would have a question about the creation of a triangulation. Is it possible to use the 'FunctionManifold' class to create a boundary described by an analytical function? If so, how can I attach this manifold and "substitute" for instance the default straight boundary of
