◆ PeriodicBoundary() [2/3]
Copy constructor, with option for the copy to represent an inverse transformation.

|
Constructor taking a reference to the translation vector.
◆ clone()
If we want the DofMap to be able to make copies of references and store them in the underlying map, this class must be clone'able, i.e.
have a kind of virtual construction mechanism.
Implements libMesh::PeriodicBoundaryBase.
◆ get_corresponding_pos()
| virtual Point libMesh::PeriodicBoundary::get_corresponding_pos |
( |
const Point & |
pt | ) |

This function should be overridden by derived classes to define how one finds corresponding nodes on the periodic boundary pair.
Implements libMesh::PeriodicBoundaryBase.
◆ get_transformation_matrix()
| const DenseMatrix<Real>& libMesh::PeriodicBoundaryBase::get_transformation_matrix |
( |
| ) |
const |
|

Get the transformation matrix, if it is defined.
Throw an error if it is not defined.
◆ get_variables()
| const std::set<unsigned int>& libMesh::PeriodicBoundaryBase::get_variables |
( |
| ) |
const |
|
inherited |
Get the set of variables for this periodic boundary condition.

- Returns
- true if _transformation_matrix is not null.

Set the transformation matrix.
When calling this method we require the following conditions: 1) matrix is square with size that matches this->variables.size() 2) the list of variables in this->variables set must all have the same FE type Both of these conditions are asserted in DBG mode.

◆ _transformation_matrix
| std::unique_ptr<DenseMatrix<Real> > libMesh::PeriodicBoundaryBase::_transformation_matrix |
|

A DenseMatrix that defines the mapping of variables on this boundary and the counterpart boundary.
This is necessary for periodic-boundaries with vector-valued quantities (e.g. velocity or displacement) on a sector of a circular domain, for exaple, since in that case we must map each variable to a corresponding linear combination of all the variables. We store the DenseMatrix via a unique_ptr, and an uninitialized pointer is treated as equivalent to the identity matrix.
