Detailed Description

template<int dim, int spacedim = dim>
class ParsedDirichletBCs< dim, spacedim >

Parsed DirichletBCs.

This class allows to set dirichlet boundary conditions, in the strong formulation, from a parameter file.

This class is derived from ParsedMappedFunctions.

The VectorTools::interpolate_boundary_values and VectorTools::project_boundary_values functions of the deal.II library have been wrapped.

A typical usage of this class is the following

// the following variables are set just for the sake of completeness
unsigned int dim = 2;
unsigned int spacedim = 2;
unsigned int n_components = 3; // number of components of the problem
// create parsed_dirichlet object
ParsedDirichletBCs<dim,spacedim>
   parsed_dirichlet("Dirichlet BCs", // name for the section of the Parameter Handler to use
                    n_components,    // number of components of the problem
                    "u,u,p",         // names of known components that can be used instead of component numbers
                    "0=u % 1=2 % 3=u.N % 6=ALL", // boundary_id = component;other_component % other_id = comp; other_comp
                    "0=x;y;0 % 1=0;0;0 % 3=x;2;0 % 6=y*k;0;k", // boundary_id = expression % other_id = other_expression
                    "k=1"); // list of constants that can be used in the above epressions
...
QGauss<dim-1> quadrature(2);
MappingQ1<dim> mapping;
std::map<types::global_dof_index,double> dirichlet_dofs;
ConstraintMatrix constraints;
...
// the following functions apply the boundary conditions for the
// boundary ids 0,1,6
parsed_dirichlet.interpolate_boundary_values(dof_handler,dirichlet_dofs);
...

// in order to apply the boundary conditions also to the
// boundary id 3, where the normal component is set,
// the following function must be called

§ ParsedDirichletBCs()

template<int dim, int spacedim>

ParsedDirichletBCs< dim, spacedim >::ParsedDirichletBCs	(	const std::string &	name = `"Dirichlet BCs"`,
		const unsigned int &	n_components = `1`,
		const std::string &	component_names = `""`,

		const std::string &	default_id_functions = `""`,
		const std::string &	default_constants = `""`
	)

Constructor.

It takes:

the name for the section of the Parameter Handler to use
the names of known components that can be used instead of component numbers
a list of ids and components where the boundary conditions must be applied, which is a string with the following pattern boundary_id = component;other_component % other_id = comp; other_comp
a list of ids and exprssions defined over the ids (if this string is left empty, homogeneous boundary conditions are imposed on the above specified ids and components)
list of constants that can be used in the above epressions
