Member Function Documentation

computeLumpedMassMatrix()

void oofem::LTRSpace::computeLumpedMassMatrix ( FloatMatrix & answer, TimeStep * tStep )

overridevirtual

Computes lumped mass matrix of receiver. Default implementation returns lumped consistent mass matrix. Then returns lumped mass transformed into nodal coordinate system. The lumping procedure zeroes all off-diagonal members and zeroes also all diagonal members corresponding to non-displacement DOFs. Such diagonal matrix is then rescaled, to preserve the element mass. Requires the computeNmatrixAt and giveMassMtrxIntegrationgMask services to be implemented.

Parameters

answer	Lumped mass matrix.
tStep	Time step.
