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 136 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 161 of file exceptions.cc.

◆ get_exc_name()

const char * ExceptionBase::get_exc_name ( ) const
inherited

Get exception name.

Definition at line 173 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 181 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 StandardExceptions::ExcMPI, internal::NoPermutation< T, N >, LACExceptions::ExcPETScError, and SolverControl::NoConvergence.

Definition at line 213 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 221 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 322 of file exceptions.cc.

Member Data Documentation

◆ distorted_cells

template<int dim, int spacedim = dim>
std::list<typename Triangulation<dim, spacedim>::cell_iterator> Triangulation< dim, spacedim >::DistortedCellList::distorted_cells

unsigned int ExceptionBase::line
protectedinherited

Line number in this file.

Definition at line 127 of file exceptions.h.

◆ function

const char* ExceptionBase::function
protectedinherited

Name of the function, pretty printed.

Definition at line 132 of file exceptions.h.

◆ cond

const char* ExceptionBase::cond
protectedinherited

The violated condition, as a string.

Definition at line 137 of file exceptions.h.

◆ exc

const char* ExceptionBase::exc
protectedinherited

Name of the exception and call sequence.

Definition at line 142 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 148 of file exceptions.h.

◆ raw_stacktrace

void* ExceptionBase::raw_stacktrace[25]
protectedinherited

Array of pointers that contains the raw stack trace.

Definition at line 154 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 168 of file exceptions.h.
