Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM, unsigned PROBLEM_DIM>
class AbstractDynamicLinearPdeSolver< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >

Abstract class for dynamic linear PDE solves. This class defines the Solve() method. The concrete class should implement the SetupLinearSystem() method (defined in AbstractLinearPdeSolver), based on the PDE being solved and the numerical method.

AbstractDynamicLinearPdeSolver< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::AbstractDynamicLinearPdeSolver ( AbstractTetrahedralMesh< ELEMENT_DIM, SPACE_DIM > * pMesh )

Constructor.

Parameters

pMesh the mesh

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM, unsigned PROBLEM_DIM>

void AbstractDynamicLinearPdeSolver< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::InitialiseHdf5Writer ( )

protected

Create and initialise the HDF5 writer. Called by Solve() if results are to be output.

Note: For now, writing variable names as 'Variable_0' etc; in the future, could allow user to specify units of time and names and units of dependent variables to be passed to the writer using DefineVariable() and DefineUnlimitedDimension()

void AbstractDynamicLinearPdeSolver< ELEMENT_DIM, SPACE_DIM, PROBLEM_DIM >::SetInitialCondition ( Vec initialCondition )

Set the initial condition.

Note: We do *not* take responsibility for destroying this vector - the caller must do so once the solver is no longer in use.

Parameters

initialCondition the initial condition
