◆ newDofHandling()

bool oofem::CBS::newDofHandling ( )

inlineoverridevirtual

Temporary method for allowing code to seamlessly convert from the old to new way of handling DOF values. (the new way expects the field to store all values, regardless of if they are computed, from BC, or IC.) This is used by MasterDof

Todo: When all models have converted to using a field, this should be removed.

◆ printDofOutputAt()

void oofem::CBS::printDofOutputAt	(	FILE *	stream,

overridevirtual

DOF printing routine. Called by DofManagers to print Dof specific part. Dof class provides component printing routines, but emodel is responsible for what will be printed at DOF level.

Parameters

stream	output stream
iDof	dof to be processed
tStep	solution step

◆ restoreContext()

void oofem::CBS::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

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

Exceptions

ContextIOERR exception if error encountered.

Reimplemented from oofem::EngngModel.

Definition at line 487 of file cbs.C.

References oofem::CIO_OK, prescribedTractionPressure, and THROW_CIOERR.

◆ saveContext()

void oofem::CBS::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()

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.

◆ updateDomainLinks()

void oofem::CBS::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::CBS::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).
