void oofem::QTrPlaneStress2dXFEM::computeBHmatrixAt	(	GaussPoint *	gp,
		FloatMatrix &	answer
	)

virtual

Computes a matrix which, multiplied by the column matrix of nodal displacements, gives the displacement gradient stored by columns.

The components of this matrix are derivatives of the shape functions, but they are arranged in a somewhat different way from the usual B matrix.

Parameters

gp	Integration point.
answer	BF matrix at this point.

		FloatMatrix &	answer,
		int	lowerIndx = `1`,

	)

virtual

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).

		TimeStep *	tStep,

		const double *	ipDensity = `NULL`
	)

inlinevirtual

Computes consistent mass matrix of receiver using numerical integration over element volume.

Mass matrix is computed as $M = \int_V N^{\mathrm{T}} \rho N dV$ , where $ N $ is displacement approximation matrix. The number of necessary integration points is determined using this->giveNumberOfIPForMassMtrxIntegration service. Only selected degrees of freedom participate in integration of mass matrix. This is described using dof mass integration mask. This mask is obtained from this->giveMassMtrxIntegrationgMask service. The nonzero mask value at i-th position indicates that i-th element DOF participates in mass matrix computation. The result is in element local coordinate system.

Parameters

answer	Mass matrix.
tStep	Time step.
mass	Total mass of receiver.

If element requests dofs using node mask which are not in node then error is generated. This masking allows node to be shared by different elements with different dofs in same node. Elements local code numbers are extracted from node using this mask. Must be defined by particular element.
