◆ computeBMatrixAt()

void oofem::PlaneStressStructuralElementEvaluator::computeBMatrixAt	(	FloatMatrix &	answer,
		GaussPoint *	gp )

overrideprotectedvirtual

Assembles the strain-displacement matrix of the receiver at given integration point. In case of IGAElements, B is assumed to contain only contribution from nonzero interpolation functions.

Implements oofem::StructuralElementEvaluator.
