◆ requiresEquationRenumbering()

bool oofem::NonStationaryTransportProblem::requiresEquationRenumbering ( TimeStep * tStep )

inlineoverridevirtual

Returns true if equation renumbering is required for given solution step. This may of course change the number of equation and in general there is no guarantee that for a certain dof the same equation will be assigned. So the use of DOF unknowns dictionaries is generally recommended.

void oofem::NonStationaryTransportProblem::restoreContext	(	DataStream &	stream,

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

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

Exceptions

ContextIOERR exception if error encountered.

◆ saveContext()

void oofem::NonStationaryTransportProblem::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

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

Exceptions

ContextIOERR If error encountered.

◆ solveYourselfAt()

void oofem::NonStationaryTransportProblem::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.

Todo: missing this->updateInternalState(& TauStep);

◆ updateDomainLinks()

void oofem::NonStationaryTransportProblem::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.

◆ updateYourself()

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

overridevirtual

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).
