Detailed Description

template<int dim, int spacedim = dim>
struct Triangulation< dim, spacedim >::DistortedCellList

A structure that is used as an exception object by the create_triangulation() function to indicate which cells among the coarse mesh cells are inverted or severely distorted (see the entry on distorted cells in the glossary).

Objects of this kind are thrown by the create_triangulation() and execute_coarsening_and_refinement() functions, and they can be caught in user code if this condition is to be ignored. Note, however, that such exceptions are only produced if the necessity for this check was indicated when calling the constructor of the Triangulation class.

A cell is called deformed if the determinant of the Jacobian of the mapping from reference cell to real cell is negative at least at one vertex. This computation is done using the GeometryInfo::jacobian_determinants_at_vertices function.

Constructor & Destructor Documentation

~DistortedCellList()

template<int dim, int spacedim = dim>

virtual Triangulation< dim, spacedim >::DistortedCellList::~DistortedCellList ( )

overridevirtualnoexcept

Destructor. Empty, but needed for the sake of exception specification, since the base class has this exception specification and the automatically generated destructor would have a different one due to member objects.

Member Function Documentation

set_fields()

void ExceptionBase::set_fields ( const char * file, const int line, const char * function, const char * cond, const char * exc_name )

inherited

Set the file name and line of where the exception appeared as well as the violated condition and the name of the exception as a char pointer. This function also populates the stacktrace.

Definition at line 135 of file exceptions.cc.

what()

const char * ExceptionBase::what ( ) const

overridevirtualnoexceptinherited

Override the standard function that returns the description of the error.

Definition at line 160 of file exceptions.cc.

get_exc_name()

const char * ExceptionBase::get_exc_name ( ) const

inherited

Get exception name.

Definition at line 172 of file exceptions.cc.

print_exc_data()

void ExceptionBase::print_exc_data ( std::ostream & out ) const

inherited

Print out the general part of the error information.

Definition at line 180 of file exceptions.cc.

print_info()

void ExceptionBase::print_info ( std::ostream & out ) const

virtualinherited

Print more specific information about the exception which occurred. Overload this function in your own exception classes.

Reimplemented in internal::NoPermutation< T >, LACExceptions::ExcPETScError, SolverControl::NoConvergence, and StandardExceptions::ExcMPI.

Definition at line 232 of file exceptions.cc.

print_stack_trace()

void ExceptionBase::print_stack_trace ( std::ostream & out ) const

inherited

Print a stacktrace, if one has been recorded previously, to the given stream.

Definition at line 240 of file exceptions.cc.

generate_message()

void ExceptionBase::generate_message ( ) const

privateinherited

Internal function that generates the c_string. Called by what().

Definition at line 341 of file exceptions.cc.

protectedinherited

Name of the exception and call sequence.

Definition at line 149 of file exceptions.h.

n_stacktrace_frames

int ExceptionBase::n_stacktrace_frames

protectedinherited

The number of stacktrace frames that are stored in the following variable. Zero if the system does not support stack traces.

Definition at line 155 of file exceptions.h.

raw_stacktrace

void* ExceptionBase::raw_stacktrace[25]

protectedinherited

Array of pointers that contains the raw stack trace.

Definition at line 161 of file exceptions.h.

what_str

std::string ExceptionBase::what_str

mutableprivateinherited

A pointer to the c_string that will be printed by what(). It is populated by generate_message()

Definition at line 175 of file exceptions.h.
