◆ computeBHmatrixAt()

void oofem::Structural3DElement::computeBHmatrixAt ( GaussPoint * gp,
FloatMatrix & answer )

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
gpIntegration point.
answerBF matrix at this point.

◆ computeBmatrixAt()

void oofem::Structural3DElement::computeBmatrixAt ( GaussPoint * gp,
FloatMatrix & answer,
int lowerIndx = 1,
int upperIndx = ALL_STRAINS )
overrideprotectedvirtual

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
gpIntegration point for which answer is computed.
answerGeometric matrix of receiver.
lowerIndxIf 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).
upperIndxIf 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).

◆ giveCharacteristicLength()

double oofem::Structural3DElement::giveCharacteristicLength ( const FloatArray & normalToCrackPlane)
overridevirtual

Returns the size of element in the given direction, in some cases adjusted (e.g. if the direction is perpendicular to a planar element). Required by material models relying on the crack-band approach to achieve objectivity with respect to the mesh size.

Parameters
normalToCrackPlaneNormal to the expected crack band.
Returns
Element size corresponding to the given direction (expected width of the crack band).

◆ giveDofManDofIDMask()

void oofem::Structural3DElement::giveDofManDofIDMask ( int inode,
IntArray & answer ) const
overridevirtual

Returns dofmanager dof mask for node. This mask defines the dofs which are used by element in node. Mask influences the code number ordering for particular node. Code numbers are ordered according to node order and dofs belonging to particular node are ordered according to this mask. 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.

Parameters
inodeMask is computed for local dofmanager with inode number.
answerMask for node.

◆ giveEdgeDofMapping()

void oofem::Structural3DElement::giveEdgeDofMapping ( IntArray & answer,
int iEdge ) const
overrideprotectedvirtual

Assembles edge dof mapping mask, which provides mapping between edge local DOFs and "global" element DOFs. Mask can be imagined as local edge code numbers used to localize local edge DOFs to element DOFs.

Parameters
answerEdge DOF mapping.
iEdgeEdge number.

◆ giveMaterialMode()

MaterialMode oofem::Structural3DElement::giveMaterialMode ( )

◆ giveSurfaceDofMapping()

void oofem::Structural3DElement::giveSurfaceDofMapping ( IntArray & answer,
int iSurf ) const
overrideprotectedvirtual

Assembles surface dof mapping mask, which provides mapping between surface local DOFs and "global" element DOFs. Mask can be imagined as local surface code numbers used to localize local DOFs to element DOFs.

Parameters

Tests if the element implements required extension. ElementExtension type defines the list of all available element extensions.

Parameters
extExtension to be tested.
Returns
Nonzero if extension supported.
