Detailed Description

This class implements an adaptive linear static engineering problem. Multiple loading cases are not supported. Due to linearity of a problem, the complete reanalysis from the beginning is done after adaptive remeshing. Solution steps represent a series of adaptive analyses.

Member Function Documentation

giveClassName()

const char * oofem::AdaptiveLinearStatic::giveClassName ( ) const

inlineoverridevirtual

Returns class name of the receiver.

Implements oofem::EngngModel.

giveInputRecordName()

const char * oofem::AdaptiveLinearStatic::giveInputRecordName ( ) const

inlineoverridevirtual

Reimplemented from oofem::LinearStatic.

References _IFT_AdaptiveLinearStatic_Name.

initializeAdaptive()

int oofem::AdaptiveLinearStatic::initializeAdaptive ( int tStepNumber )

overridevirtual

Initializes the newly generated discretization state according to previous solution. This process should typically include restoring old solution, instanciating newly generated domain(s) and by mapping procedure.

Reimplemented from oofem::EngngModel.

Definition at line 92 of file adaptlinearstatic.C.

initializeFrom()

void oofem::AdaptiveLinearStatic::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.

Reimplemented from oofem::EngngModel.

References _IFT_AdaptiveLinearStatic_meshpackage, IR_GIVE_OPTIONAL_FIELD, and meshPackage.

printOutputAt()

void oofem::AdaptiveLinearStatic::printOutputAt ( FILE * file, TimeStep * tStep )

overridevirtual

Prints output of receiver to output domain stream, for given time step. Corresponding function for element gauss points is invoked (gaussPoint::printOutputAt).

Reimplemented from oofem::EngngModel.

Definition at line 80 of file adaptlinearstatic.C.

References oofem::EngngModel::defaultErrEstimator, oofem::EngngModel::giveDomain(), and oofem::relativeErrorEstimateEEV.

restoreContext()

void oofem::AdaptiveLinearStatic::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 131 of file adaptlinearstatic.C.

updateDomainLinks()

void oofem::AdaptiveLinearStatic::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.

Definition at line 155 of file adaptlinearstatic.C.

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

updateYourself()

void oofem::AdaptiveLinearStatic::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).

Reimplemented from oofem::EngngModel.
