void oofem::QTrPlaneStressGrad::computeBkappaMatrixAt ( GaussPoint gp,
FloatMatrix answer 
)
protectedvirtual
void oofem::QTrPlaneStressGrad::computeGaussPoints ( )
protectedvirtual

Initializes the array of integration rules member variable.

Element can have multiple integration rules for different tasks. For example structural element family class uses this feature to implement transparent support for reduced and selective integration of some strain components. Must be defined by terminator classes.

virtual int oofem::QTrPlaneStressGrad::computeNumberOfDofs ( )

Computes or simply returns total number of element's local DOFs.

Must be defined by particular element.

Returns
Number of local DOFs of element.

virtual void oofem::QTrPlaneStressGrad::computeStiffnessMatrix ( FloatMatrix answer,
MatResponseMode  rMode,
TimeStep tStep 
)
inlineprotectedvirtual

Computes the stiffness matrix of receiver.

The response is evaluated using $ \int B_{\mathrm{H}}^{\mathrm{T}} D B_{\mathrm{H}} \;\mathrm{d}v $, where $ B_{\mathrm{H}} $ is the B-matrix which produces the displacement gradient vector $ H_{\mathrm{V}} $ when multiplied with the solution vector a. Reduced integration are taken into account.

Parameters
answerComputed stiffness matrix.
rModeResponse mode.
tStepTime step.
Todo:
We probably need overloaded function (like above) here as well.

void oofem::QTrPlaneStressGrad::giveDofManDofIDMask ( int  inode,
IntArray answer 
) const
protectedvirtual

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.

Evaluates nodal representation of real internal forces.

Necessary transformations are taken into account.

Todo:
what is meant?
Parameters
answerEquivalent nodal forces vector.
tStepTime step
useUpdatedGpRecordIf equal to zero, the stresses in integration points are computed (slow but safe).
Todo:
Is this really what we should do for inactive elements?
Todo:
This is actaully inefficient since it constructs B and twice and collects the nodal unknowns over and over.
Todo:
is this check really necessary?
