assemble() [1/3]

virtual void Dumux::LocalStiffness< TypeTag, m >::assemble ( const Entity & e, int k = 1 )

pure virtualinherited

Assembles local stiffness matrix including boundary conditions for given element and order.

On exit the following things have been done:

• The stiffness matrix for the given entity and polynomial degree has been assembled and is accessible with the mat() method.
• The boundary conditions have been evaluated and are accessible with the bc() method. The boundary conditions are either neumann, process or dirichlet. Neumann indicates that the corresponding node (assuming a nodal basis) is at the Neumann boundary, process indicates that the node is at a process boundary (arising from the parallel decomposition of the mesh). Process boundaries are treated as homogeneous Dirichlet conditions, i.e. the corresponding value in the right hand side is set to 0. Finally, Dirichlet indicates that the node is at the Dirichlet boundary.
• The right hand side has been assembled. It contains either the value of the essential boundary condition or the assembled source term and neumann boundary condition. It is accessible via the rhs() method.

Parameters

e	a codim 0 entity reference
k	order of Lagrange basis (default is 1)

assemble() [2/3]

template<class TypeTag>

void Dumux::MimeticTwoPLocalStiffness< TypeTag >::assemble ( const Element & cell, const Dune::BlockVector< VBlockType > & localSolution, int orderOfShapeFns = 1 )

assemble() [3/3]

template<class TypeTag>

void Dumux::MimeticTwoPLocalStiffness< TypeTag >::assemble ( const Element & element, int k = 1 )

inline

Assembles local stiffness matrix for given element and order.

On exit the following things have been done:

• The stiffness matrix for the given entity and polynomial degree has been assembled and is accessible with the mat() method.
• The boundary conditions have been evaluated and are accessible with the bc() method
• The right hand side has been assembled. It contains either the value of the essential boundary condition or the assembled source term and Neumann boundary condition. It is accessible via the rhs() method.

Parameters

element	a codim 0 entity reference
k	order of CR basis (only k = 1 is implemented)

assembleBoundaryCondition() [1/2]

virtual void Dumux::LocalStiffness< TypeTag, m >::assembleBoundaryCondition ( const Entity & e, int k = 1 )

pure virtualinherited

assemble only boundary conditions for given element and order

On exit the following things have been done:

• The boundary conditions have been evaluated and are accessible with the bc() method. The boundary conditions are either Neumann, process or Dirichlet. Neumann indicates that the corresponding node (assuming a nodal basis) is at the Neumann boundary, process indicates that the node is at a process boundary (arising from the parallel decomposition of the mesh). Process boundaries are treated as homogeneous Dirichlet conditions, i.e. the corresponding value in the right hand side is set to 0. Finally, Dirichlet indicates that the node is at the Dirichlet boundary.
• The right hand side has been assembled as far as boundary conditions are concerned. It contains either the value of the essential boundary condition or the assembled Neumann boundary condition. It is accessible via the rhs() method.

Parameters

e	a codim 0 entity reference
k	order of Lagrange basis (default is 1)

template<class TypeTag>

inline

On exit the following things have been done:
