Member Function Documentation

int oofem::StationaryTransportProblem::checkConsistency ( )

virtual

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

Returns

Nonzero if receiver check is o.k.

Reimplemented from oofem::EngngModel.

Reimplemented in oofem::NonStationaryTransportProblem.

Definition at line 304 of file stationarytransportproblem.C.

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

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

inlinevirtual

Returns class name of the receiver.

Implements oofem::EngngModel.

Reimplemented in oofem::NonStationaryTransportProblem, and oofem::NLTransientTransportProblem.

Definition at line 98 of file stationarytransportproblem.h.

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

virtual

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.

virtual fMode oofem::StationaryTransportProblem::giveFormulation ( )

inlinevirtual

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.

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

virtual

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.

Reimplemented from oofem::EngngModel.

IRResultType oofem::StationaryTransportProblem::initializeFrom ( InputRecord *  ir )

virtual

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.

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

virtual

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

stream	Context file.
mode	Determines amount of info in stream.

Returns

contextIOResultType.

Exceptions

ContextIOERR

exception if error encountered.

Reimplemented from oofem::EngngModel.

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

virtual

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

stream	Context stream.
mode	Determines amount of info in stream.

Returns

contextIOResultType.

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

virtual

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.

void oofem::StationaryTransportProblem::updateComponent ( TimeStep *  tStep, NumericalCmpn  cmpn, Domain *  d  )

virtual

Updates components mapped to numerical method if necessary during solution process.

Some numerical methods may require updating mapped components during solution process (e.g., updating of tangent stiffness when using updated Newton-Raphson method).

Parameters

tStep	Time when component is updated.
cmpn	Numerical component to update.
d	Domain.

void oofem::StationaryTransportProblem::updateDomainLinks ( )

virtual

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.

void oofem::StationaryTransportProblem::updateInternalState ( TimeStep *  tStep )

protectedvirtual

Updates IP values on elements.

Parameters

tStep

Solution step.

Todo:

Remove this, unnecessary with solving as a nonlinear problem (left for now, since nonstationary problems might still need it)

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

virtual

Updates internal state after finishing time step.

(for example total values may be updated according to previously solved increments). Then element values are also updated (together with related integration points and material statuses).
