◆ giveUnknownComponent()

double oofem::EigenValueDynamic::giveUnknownComponent	(	ValueModeType	,
		TimeStep *	,

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.

◆ giveUnknownDictHashIndx()

int oofem::EigenValueDynamic::giveUnknownDictHashIndx	(	ValueModeType	mode,

overridevirtual

This method is responsible for computing unique dictionary id (ie hash value) from given valueModeType and time step. This function is used by particular dofs to access unknown identified by given parameters from its dictionary using computed index. Usually the hash algorithm should produce index that depend on time step relatively to actual one to avoid storage of complete history.

◆ newDofHandling()

bool oofem::EigenValueDynamic::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.

Reimplemented from oofem::EngngModel.

Definition at line 91 of file eigenvaluedynamic.h.

◆ printOutputAt()

void oofem::EigenValueDynamic::printOutputAt	(	FILE *	file,

◆ restoreContext()

void oofem::EigenValueDynamic::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 265 of file eigenvaluedynamic.C.

References oofem::CIO_OK, eigVal, field, and THROW_CIOERR.

◆ saveContext()

void oofem::EigenValueDynamic::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.

◆ solveYourself()

void oofem::EigenValueDynamic::solveYourself ( )

overridevirtual

Starts solution process. Implementation should invoke for each time step solveYourselfAt function with time step as parameter. Time steps are created using giveNextStep function (this will set current time step to newly created, and updates previous step).

Reimplemented from oofem::EngngModel.

Definition at line 154 of file eigenvaluedynamic.C.

◆ updateYourself()

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