## 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.

## ◆ ~DistortedCellList()

template<int dim, int spacedim>
 Triangulation< dim, spacedim >::DistortedCellList::~DistortedCellList ( )
overridevirtualdefaultnoexcept

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.

## ◆ 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 128 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 151 of file exceptions.cc.

## ◆ get_exc_name()

 const char * ExceptionBase::get_exc_name ( ) const
inherited

Get exception name.

Definition at line 174 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 182 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.

Definition at line 214 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 222 of file exceptions.cc.

## ◆ distorted_cells

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

A list of those cells among the coarse mesh cells that are deformed or whose children are deformed.

Definition at line 1542 of file tria.h.

## ◆ file

 const char* ExceptionBase::file
protectedinherited

Name of the file this exception happens in.

Definition at line 122 of file exceptions.h.

## ◆ line

 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.

## ◆ stacktrace

 char** ExceptionBase::stacktrace
mutableprotectedinherited

A backtrace to the position where the problem happened, if the system supports this.

Definition at line 148 of file exceptions.h.

## ◆ n_stacktrace_frames

 int ExceptionBase::n_stacktrace_frames
protectedinherited

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

Definition at line 154 of file exceptions.h.

## ◆ raw_stacktrace

 void* ExceptionBase::raw_stacktrace[25]
protectedinherited

array of pointers that contains the raw stack trace

Definition at line 160 of file exceptions.h.
