void oofem::Lattice2d::computeBmatrixAt	(	GaussPoint *	gp,
		FloatMatrix &	answer,
		int	lowerIndx = `1`,
		int	upperIndx = `ALL_STRAINS`
	)

protectedvirtual

Computes the geometrical matrix of receiver in given integration point.

The product of this matrix (assembled at given integration point) and element displacement vector is element strain vector. If lowerIndx and upperIndx parameters are specified, answer is formed only for strains within this interval. This will affects the size of answer.

Parameters

gp	Integration point for which answer is computed.
answer	Geometric matrix of receiver.
lowerIndx	If specified, answer is formed only for strain with index equal and greater than lowerIndx. This parameter has default value 1 (answer is formed from first strain).
upperIndx	If specified, answer is formed only for strain with index less and equal than upperIndx. This parameter has default value ALL_STRAINS (answer is formed for all strains).

void oofem::Lattice2d::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep
	)

protectedvirtual

Computes numerically stiffness matrix of receiver.

Default implementation computes element stiffness using $K=\int_v B^{\mathrm{T}} D B \mathrm{d}V$ formulae, where $ B $ is element geometric matrix and $ D $ is material stiffness matrix. No geometrical nonlinearity is taken into account. NUmerical integration procedure uses integrationRulesArray for numerical integration. Support for reduced or selected integration is implemented. The individual integration rules are assumed to correspond to different terms from which the overall matrix is assembled.

If there is one integration rule, the full integration of all coefficients is performed. Otherwise, integration is performed using following rules. Each integration rule can specify start and end strain index of strain vector components for which is valid. It is necessary to ensure that these start and end indexes, dividing geometrical matrix into blocks, are not overlapping and that each strain component is included.

Then stiffness matrix is obtained as summation of integrals $I_{ij}=\int_v B^{\mathrm{T}}_i D_{ij} B_j \mathrm{d}V$ where $ B_i $ is i-th block of geometrical matrix and $D_{ij}$ is corresponding constitutive sub-matrix. The geometrical matrix is obtained using computeBmatrixAt service and the constitutive matrix is obtained using computeConstitutiveMatrixAt service. The $I_{ij}$ integral is evaluated using such integration rule, which is valid for i-th or j-th block and has smaller number of integration points.

For higher numerical performance, only one half of stiffness matrix is computed and answer is then symmetrized. Therefore, if element matrix will be generally nonsymmetric, one must specialize this method. Finally, the result is transformed into global coordinate system (or nodal coordinate system, if it is defined).

Parameters

answer	Computed stiffness matrix (symmetric).
rMode	Response mode.
tStep	Time step.

Returns dofmanager dof mask for node.
