oofem::StationaryTransportProblem::StationaryTransportProblem ( int i,
EngngModel * _master = nullptr )

Member Function Documentation

◆ checkConsistency()

int oofem::StationaryTransportProblem::checkConsistency ( )
overridevirtual

Allows programmer to test some receiver's internal data, before computation begins.

Returns
Nonzero if receiver check is o.k.

Reimplemented from oofem::EngngModel.

Definition at line 295 of file stationarytransportproblem.C.

References oofem::EngngModel::giveDomain(), oofem::Domain::giveElements(), and OOFEM_WARNING.

◆ giveClassName()

const char * oofem::StationaryTransportProblem::giveClassName ( ) const
inlineoverridevirtual

Returns class name of the receiver.

Implements oofem::EngngModel.

Definition at line 97 of file stationarytransportproblem.h.

◆ giveField()

FieldPtr oofem::StationaryTransportProblem::giveField ( FieldType key,
TimeStep *  )
overridevirtual

Returns the smart pointer to requested field, Null otherwise. The return value uses shared_ptr, as some registered fields may be owned (and maintained) by emodel, while some may be created on demand and thus reliable reference counting mechanism is essential.

Reimplemented from oofem::EngngModel.

Definition at line 117 of file stationarytransportproblem.C.

References oofem::EngngModel::giveCurrentStep(), OOFEM_ERROR, and UnknownsField.

◆ giveFormulation()

fMode oofem::StationaryTransportProblem::giveFormulation ( )
inlineoverridevirtual

Indicates type of non linear computation (total or updated formulation). This is used for example on Nodal level to update coordinates if updated formulation is done, or on element level, when non linear contributions are computed.

Reimplemented from oofem::EngngModel.

◆ giveInputRecordName()

const char * oofem::StationaryTransportProblem::giveInputRecordName ( ) const
inline

Definition at line 96 of file stationarytransportproblem.h.

References _IFT_StationaryTransportProblem_Name.

◆ giveNextStep()

TimeStep * oofem::StationaryTransportProblem::giveNextStep ( )
overridevirtual

Returns next time step (next to current step) of receiver.

Reimplemented from oofem::EngngModel.

◆ giveNumericalMethod()

NumericalMethod * oofem::StationaryTransportProblem::giveNumericalMethod ( MetaStep * mStep)
overridevirtual

Returns reference to receiver's numerical method.

Reimplemented from oofem::EngngModel.

Definition at line 60 of file stationarytransportproblem.C.

References oofem::EngngModel::giveDomain(), and nMethod.

Referenced by solveYourselfAt(), and updateDomainLinks().

◆ giveUnknownComponent()

double oofem::StationaryTransportProblem::giveUnknownComponent ( ValueModeType ,
TimeStep * ,
Domain * ,
Dof *  )
overridevirtual

Returns requested unknown. Unknown at give time step is characterized by its type and mode and by its equation number. This function is used by Dofs, when they are requested for their associated unknowns.

Dof::giveUnknown

Reimplemented from oofem::EngngModel.

References oofem::Dof::__giveEquationNumber(), OOFEM_ERROR, and UnknownsField.

◆ initializeFrom()

void oofem::StationaryTransportProblem::initializeFrom ( InputRecord & ir)
overridevirtual

Initializes receiver according to object description in input reader. InitString can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.

Todo
Combine this option with structural problems, where it is possible to keep the secant tangent elastic tangent (or generally, the initial tangent) etc. One option should fit all common needs here.

◆ restoreContext()

void oofem::StationaryTransportProblem::restoreContext ( DataStream & stream,
ContextMode mode )
overridevirtual

Restores the state of model from output stream. Restores not only the receiver state, but also same function is invoked for all DofManagers and Elements in associated domain. Note that by restoring element context also contexts of all associated integration points (and material statuses) are restored. Each context is associated with unique time step. Only one context per time step is allowed. Restore context function will restore such context, which is related (through its step number) to time step number and version given in obj parameter. Restoring context will change current time step in order to correspond to newly restored context.

Parameters
streamContext file.
modeDetermines amount of info in stream.
Exceptions
ContextIOERRexception if error encountered.

Reimplemented from oofem::EngngModel.

Definition at line 287 of file stationarytransportproblem.C.

References UnknownsField.

◆ saveContext()

void oofem::StationaryTransportProblem::saveContext ( DataStream & stream,
ContextMode mode )
overridevirtual

Stores the state of model to output stream. Stores not only the receiver state, but also same function is invoked for all DofManagers and Elements in associated domain. Note that by storing element context also contexts of all associated integration points (and material statuses) are stored.

Parameters
streamContext stream.
modeDetermines amount of info in stream.
Exceptions
ContextIOERRIf error encountered.

Reimplemented from oofem::EngngModel.

Definition at line 279 of file stationarytransportproblem.C.

◆ solveYourselfAt()

void oofem::StationaryTransportProblem::solveYourselfAt ( TimeStep * tStep)
overridevirtual

Solves problem for given time step. Should assemble characteristic matrices and vectors if necessary and solve problem using appropriate numerical method. After finishing solution, this->updateYourself function for updating solution state and then this->terminate function (for updating nodal and element values) should be called.

Reimplemented from oofem::EngngModel.

◆ updateComponent()

◆ updateDomainLinks()

void oofem::StationaryTransportProblem::updateDomainLinks ( )
overridevirtual

Updates domain links after the domains of receiver have changed. Used mainly after restoring context - the domains may change and this service is then used to update domain variables in all components belonging to receiver like error estimators, solvers, etc, having domains as attributes.

Reimplemented from oofem::EngngModel.

◆ updateInternalRHS()

void oofem::StationaryTransportProblem::updateInternalRHS ( FloatArray & answer,
TimeStep * tStep,
Domain * d,
FloatArray * eNorm )
overridevirtual

Updates the solution (guess) according to the new values. Callback for nonlinear solvers (e.g. Newton-Raphson).

Parameters
solutionVectorNew solution.
tStepTime when component is updated.

◆ updateMatrix()

void oofem::StationaryTransportProblem::updateMatrix ( SparseMtrx & mat,
TimeStep * tStep,
Domain * d )
overridevirtual

Updates the solution (guess) according to the new values. Callback for nonlinear solvers (e.g. Newton-Raphson).

Note
For performance, the matrix should keep it's non-zero structure between calls, so the caller should make sure not to clear the matrix object before called.
Parameters
solutionVectorNew solution.
tStepTime when component is updated.
dDomain.
