Detailed Description

This extends RBAssemblyExpansion to provide an assembly expansion for the case of time-dependent PDEs. This just requires an extra set of ElemAssembly functors for the time-derivative term.

Member Typedef Documentation

typedef std::map<std::string, std::pair<unsigned int, unsigned int> > libMesh::ReferenceCounter::Counts [protected, inherited]

Data structure to log the information. The log is identified by the class name.

Constructor & Destructor Documentation


Member Function Documentation

Attach ElemAssembly object for the left-hand side (both interior and boundary assembly).

Attach ElemAssembly object for the right-hand side (both interior and boundary assembly).

Attach ElemAssembly object for the time-derivative (both interior and boundary assembly).

void libMesh::RBAssemblyExpansion::attach_multiple_A_assembly ( std::vector< ElemAssembly * >  Aq_assembly) [inherited]

Attach multiple ElemAssembly objects for the left-hand side (both interior and boundary assembly).

void libMesh::RBAssemblyExpansion::attach_multiple_F_assembly ( std::vector< ElemAssembly * >  Fq_assembly) [inherited]

Attach multiple ElemAssembly objects for the right-hand side (both interior and boundary assembly).

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly ( std::vector< ElemAssembly * >  output_assembly) [virtual, inherited]

Attach ElemAssembly object for an output (both interior and boundary assembly). In this case we pass in vector arguments to allow for Q_l > 1.

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly ( ElemAssembly output_assembly) [virtual, inherited]

Attach ElemAssembly object for an output (both interior and boundary assembly). This function provides simpler syntax in the case that Q_l = 1; we do not need to use a vector in this case.
