Detailed Description

template<typename T>
class LinTimeAssemble< T >

Base class for linear time-dependent discretizations.

This base class is designed for time-dependent problems discretized in such a way that only a linear system is to be solved in every time step. Nevertheless, there may be non-linear terms discretized explicitly. Besides, the matrix of the linear system may depend on the solution from the old time level. (Cf. also class NLTimeAssemble<T>.)

Note:

The template depends on a type T. This type should satisfy the conditions listed in small_matrix.hpp for small matrices.

Member Function Documentation

template<typename T>

const bool& LinTimeAssemble< T >::RecompMatrix

(

)

const [inline]

Returns true if the matrix is recomputed every time step.

template<typename T>

virtual void LinTimeAssemble< T >::PrintParam

(

)

[pure virtual]

Prints parameters of the discretization.

Implemented in GenLinVcFV< T, Flux >.

template<typename T>

virtual void LinTimeAssemble< T >::AssembleMatrix	(	GridVec< T > &	u,
		SysMatrix< T > &	A,
		T	s_a
	)			[pure virtual]

Assembles the matrix.

Parameters:

[in]	u	Solution from the last time step
[in]	A	The matrix to assemble; the sizes must be set
[in]	s_a	The factor for the stiffness matrix (that for the mass matrix is 1)

Implemented in GenLinVcFV< T, Flux >.

template<typename T>

virtual void LinTimeAssemble< T >::AddExplicit	(	T	factor,
		GridVec< T > &	u,
		GridVec< T > &	v
	)			[inline, virtual]

Adds the terms implemented as explicit.

Note:

'AddExplicit' may not change 'u'. The 'factor' takes into account only the time stepping coefficients, but not the terms coming from the mass matrix.

Parameters:

[in]	factor	The factor to multiply the terms by
[in]	u	Solution from the last time step
[in]	v	The vector to add the explicit terms to (may not be 'u')
