Classes
class	ADIOS2Writer
	Base class for ADIOS2-based writers. More...

Namespaces
namespace	dolfinx
	Top-level namespace.
namespace	dolfinx::fem
	Finite element method functionality.
namespace	dolfinx::io
	Support for file IO.

Functions
template<class T >
adios2::Attribute< T >	define_attribute (adios2::IO &io, std::string name, const T &value, std::string var_name="", std::string separator="/")
	Safe definition of an attribute. First check if it has already been defined and return it. If not defined create new attribute.
template<class T >
adios2::Variable< T >	define_variable (adios2::IO &io, std::string name, const adios2::Dims &shape=adios2::Dims(), const adios2::Dims &start=adios2::Dims(), const adios2::Dims &count=adios2::Dims())
	Safe definition of a variable. First check if it has already been defined and return it. If not defined create new variable.
template<std::floating_point T>
std::shared_ptr< const mesh::Mesh< T > >	extract_common_mesh (const typename adios2_writer::U< T > &u)
	Extract common mesh from list of Functions.
void	initialize_mesh_attributes (adios2::IO &io, mesh::CellType type)
	Initialize mesh related attributes for the ADIOS2 file used in Fides.
template<std::floating_point T>
void	initialize_function_attributes (adios2::IO &io, const typename adios2_writer::U< T > &u)
	Initialize function related attributes for the ADIOS2 file used in Fides.
template<typename T , std::floating_point U>
std::vector< T >	pack_function_data (const fem::Function< T, U > &u)
	Pack Function data at vertices. The mesh and the function must both be 'P1'.
template<typename T , std::floating_point U>
void	write_data (adios2::IO &io, adios2::Engine &engine, const fem::Function< T, U > &u)
	Write a first order Lagrange function (real or complex) using ADIOS2 in Fides format. Data is padded to be three dimensional if vector and 9 dimensional if tensor.
template<std::floating_point T>
void	write_mesh (adios2::IO &io, adios2::Engine &engine, const mesh::Mesh< T > &mesh)
	Write mesh geometry and connectivity (topology) for Fides.

Variables
constexpr std::array	field_ext = {"_real", "_imag"}
	String suffix for real and complex components of a vector-valued field.
