Member Function Documentation
| const uint concepts::QuadRuleFactory::count | ( | ) | const [inline] |
Returns counter of changes.
Definition at line 240 of file quadRule.hh.
| virtual std::ostream& concepts::QuadRuleFactory::info | ( | std::ostream & | os | ) | const [protected, virtual] |
Returns information in an output stream.
Reimplemented from concepts::OutputOperator.
| const std::string concepts::QuadRuleFactory::integrationRule | ( | ) | const |
Returns information on the settings of the quadrature rule.
| QuadratureRule* concepts::QuadRuleFactory::operator() | ( | const ushort | p = 1 | ) | const |
Returns the quadrature rule, i.e.
pre-computed abscissas and weights.
Created dynamically and has to be deleted by the user.
- Parameters:
-
p maximal polynomial degree
| void concepts::QuadRuleFactory::reset | ( | ) |
Set the standard type of integration.
| void concepts::QuadRuleFactory::set | ( | enum concepts::intRule | rule, |
| bool | constant, | ||
| uint | points | ||
| ) |
Sets the integration rule.
- Parameters:
-
rule Type of integration constant Flag, true = constant number of points points Number of points, constant or to add
- Examples:
- BGT_0.cc, exactDtN.cc, inhomDirichletBCs.cc, inhomDirichletBCsLagrange.cc, inhomNeumannBCs.cc, and RobinBCs.cc.

Member Data Documentation
uint concepts::QuadRuleFactory::addNumberOfPoints_ [private] |
Number of integration points to add to approximation order when varying number of integration points is requested.
Default is 2.
Definition at line 263 of file quadRule.hh.
uint concepts::QuadRuleFactory::cnt_ [private] |
Counter for changes.
Definition at line 270 of file quadRule.hh.
uint concepts::QuadRuleFactory::constNumerOfPoints_ [private] |
Number of integration points to use when constant number is requested.
Default value is 10.
Definition at line 259 of file quadRule.hh.
enum intRule concepts::QuadRuleFactory::integrationType_ [private] |
Default behaviour: integration rule Gauss Jacobi (highest order).
The default value is 4 (Gauss Jacobi). Other possible values are 0 (Gauss Lobatto) for better graphics (connected elements). Use setIntegrationRule() to change it.
Definition at line 255 of file quadRule.hh.
bool concepts::QuadRuleFactory::useConstantNumberOfPoints_ [private] |
Use constant number of integration points (true) or not (false).
Default is false (ie. varying number of points).
