Detailed Description

Data type STable. STable is similar to Table, but it's for symmetric connectivity, i.e. TYPE I is equivalent to TYPE II. In the first dimension we put the elements with smaller index.

Definition at line 196 of file table.hpp.

Constructor & Destructor Documentation

mfem::STable::STable ( int  dim,
int  connections_per_row = 3 

Creates table with fixed number of connections.

Definition at line 554 of file table.cpp.

mfem::STable::~STable ( )

Destroys STable.

Definition at line 215 of file table.hpp.

Member Function Documentation

int mfem::STable::operator() ( int  i,
int  j 
) const

Returns index of the connection between element i of TYPE I and element j of TYPE II. If there is no connection between element i and element j established in the table, then the return value is -1.

Definition at line 558 of file table.cpp.

int mfem::STable::Push ( int  i,
int  j 

Establish connection between element i and element j in the table. The return value is the index of the connection. It returns -1 if it fails to establish the connection. Possibilities are there is not enough memory on row i to establish connection to j, an attempt to establish new connection after calling Finalize().
