Member Function Documentation

int oofem::TrPlaneStress2dXFEM::checkConsistency ( )

virtual

Performs consistency check.

This method is called at startup for all elements in particular domain. This method is intended to check data compatibility. Particular element types should test if compatible material and crossSection both with required capabilities are specified. Derived classes should provide their own analysis specific tests. Some printed input if incompatibility is found should be provided (error or warning member functions). Method can be also used to initialize some variables, since this is invoked after all domain components are instanciated.

Returns: Zero value if check fail, otherwise nonzero.

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,

	)

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.

Elements local code numbers are extracted from node using this mask. Must be defined by particular element.

virtual int oofem::TrPlaneStress2dXFEM::testElementExtension ( ElementExtension ext )

inlinevirtual

Tests if the element implements required extension.

ElementExtension type defines the list of all available element extensions.

Parameters

ext	Extension to be tested.

Returns: Nonzero if extension supported.

void oofem::TrPlaneStress2dXFEM::updateYourself ( TimeStep * tStep )

protectedvirtual

Updates element state after equilibrium in time step has been reached.

Default implementation updates all integration rules defined by integrationRulesArray member variable. Doing this, all integration points and their material statuses are updated also. All temporary history variables, which now describe equilibrium state are copied into equilibrium ones. The existing internal state is used for update.

Parameters

tStep Time step for newly reached state.
