Classes
class	libMesh::LogicError
	A class to represent the internal "this should never happen" errors, to be thrown by "libmesh_error();". More...
class	libMesh::NotImplemented
	A class to stub for features that should be in libMesh, but haven't been written yet, to be thrown by "libmesh_not_implemented();". More...
class	libMesh::FileError
	A class representing a failed attempt by the library to open a file (or construct an fstream, etc), to be thrown by "libmesh_file_error(filename);" For ease of debugging, "filename" should include any (absolute or relative or implicit) pathname that was part of the failed open. More...
class	libMesh::DegenerateMap
	A class representing the detection of an unexpected degeneracy, e.g. More...
class	libMesh::ConvergenceFailure
	A class representing a solver's failure to converge, to be thrown by "libmesh_convergence_failure();" This should be a last resort; more often, a solve which has failed should be reattempted after switching to a smaller timestep, adding underrelaxation, taking a smaller continuation step, etc. More...
class	libMesh::DynamicCastFailure
	A class representing that a dynamic cast failed to produce expected output. More...
class	libMesh::FloatingPointException
	A class representing a floating point exception. More...
class	libMesh::SolverException
	A class representing an exception during a solve. More...
class	libMesh::TerminationException
	A class representing an exception used only to send a program to the terminate handler for abort after cleanup, while bypassing the usual debugging output (performance logs, stack traces, "terminating" messages) that the handler does to ease debugging of uncaught error exceptions. More...

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

Functions
void	libMesh::libmesh_terminate_handler ()
	A terminate handler. More...
void	libMesh::enableFPE (bool on)
	Toggle hardware trap floating point exceptions. More...
void	libMesh::enableSEGV (bool on)
	Toggle libMesh reporting of segmentation faults. More...
void	libMesh::enableSIGINT (bool on)
	Toggle libMesh handling of SIGINT (Ctrl+C) interrupts. More...
