Detailed Description

The libMesh namespace provides an interface to certain functionality in the library.

Sanity check, without prior inclusion of libmesh_config.h.

Here, it provides a LibMeshInit class which uses the RAII (Resource Acquisition Is Initialization) idiom to ensure initialization of any other dependent libraries (e.g. MPI or PETSC), and to close those libraries when it goes out of scope. It also provides a centralized place for performance logging and other functionality.

This file is no typical header file. It is only to be included at the end of an implementation file, so that the proper variations of the InfFE class are instantiated.

◆ NodeConstraintRow

typedef std::map<const Node *, Real, std::less<const Node *>, Threads::scalable_allocator<std::pair<const Node * const, Real> > > libMesh::NodeConstraintRow

A row of the Node constraint mapping.

Currently this just stores the topology of the constrained Nodes, but for forward compatibility we also include coefficients, so we could add Lagrange-positioned-node constraints later.

◆ SteadyLinearSystem

◆ subdomain_id_type

typedef uint16_t libMesh::subdomain_id_type

Based on the 4-byte comment warning above, this probably doesn't work with exodusII at all...

Note: subdomain_id_type should be a positive integer, but due to a limitation in the exodusII API, we are forced to use a signed integer here to represent subdomains. This gives us 2^31 possible unique blocks.

◆ Order

enum libMesh::Order : int

defines an enum for polynomial orders.

Fixing each label to a specific int, since InfFE and p refinement may cast between them.

Note: It is possible to safely cast integral values larger than 43 to Order, provided that the cast value fits in the range of int. A potential use case for such a cast is when employing the QGrid class at extremely high order.

The fixed type, i.e. ": int", enumeration syntax used here allows this enum to be forward declared as enum Order : int; reducing header file dependencies.

◆ VariableIndexing

enum libMesh::VariableIndexing

Dirichlet functions may be indexed either by "system variable order" or "local variable order", depending on how the DirichletBoundary object is constructed.

For example, suppose a system has variables {a, b, c, d}, and a DirichletBoundary is set for variables {b, d} (i.e. variables_in is {1, 3}). If the boundary is constructed to use "system variable order", input function(s) will be queried for components 1 and 3; this is useful for reusing input functions as both exact solutions and Dirichlet boundaries in benchmark problems. If the boundary is constructed to use "local variable order", input function(s) will be queried for components 0 and 1; this is useful for flexibly constructing Dirichlet boundaries in multiphysics codes or from user input files.

◆ command_line_next()

template<typename T >

T libMesh::command_line_next	(	std::string	name,
		T	default_value

Use GetPot's search()/next() functions to get following arguments from the command line.

For backwards compatibility with past option naming conventions, libMesh searches for the given argument first in its original form, then with all underscores changed to dashes, then with all dashes (except any leading dashes) changed to underscores, and returns true if any of the above finds a match.

This routine manipulates the command_line cursor and should not be called concurrently with similar utilities in multiple threads.

◆ default_solver_package()

SolverPackage libMesh::default_solver_package ( )

Returns: The default solver interface to use. The value depends on which solver packages were available when the library was configured. The command-line is also checked, allowing the user to override the compiled default. For example, –use-petsc will force the use of PETSc solvers, and –use-laspack will force the use of LASPACK solvers.

◆ on_command_line()

bool libMesh::on_command_line ( std::string arg )

Returns: true if the argument arg was specified on the command line, false otherwise.

For backwards compatibility with past option naming conventions, libMesh searches for the given argument first in its original form, then with all underscores changed to dashes, then with all dashes (except any leading dashes) changed to underscores, and returns true if any of the above finds a match.

This routine manipulates the command_line cursor and should not be called concurrently with similar utilities in multiple threads.

template <typename U>

friend std::ostream & operator << (std::ostream & os, const SparseMatrix<U> & m);

Note: The above syntax, which does not require any prior declaration of operator<<, declares any instantiation of SparseMatrix<X> is friend to any instantiation of operator<<(ostream &, SparseMatrix<Y> &). It would not happen in practice, but in principle it means that SparseMatrix<Complex> would be friend to operator<<(ostream &, SparseMatrix<Real>).; The form below, which requires a previous declaration of the operator<<(stream &, SparseMatrix<T> &) function (see top of this file), means that any instantiation of SparseMatrix<T> is friend to the specialization operator<<(ostream &, SparseMatrix<T> &), but e.g. SparseMatrix<U> is not friend to the same function. So this is slightly different to the form above...

This method seems to be the "preferred" technique, see http://www.parashift.com/c++-faq-lite/template-friends.html

It returns a CheckpointIO object that can be used to write the mesh chunks into individual files (e.g. by calling checkpoint_obj.write(out_file_name)) - the number of files is equal to the number of chunks. This function supports MPI parallelism and can be used with several MPI procs to speed up splitting.
