Detailed Description

This class implements Incremental LinearStatic Engineering problem. Problem is solved as series of explicit linear solutions. It will solve any nonlinear problem by writing the expressions explicitly \( K({}^{n-1} r)\cdot \delta r = R({}^{n-1}r) - F \). Explicit solver has requirements on the time step size to obtain a stable solution.

This class can be used for solving linear creep problems.

Supports the changes of static scheme (applying, removing and changing boundary conditions) during the analysis.

◆ giveDiscreteTime()

double oofem::IncrementalLinearStatic::giveDiscreteTime ( int iStep )

This function returns time valid for iStep time step, used in integration of structure response. This functions, when invoked for the first time, generates table of times. Times in this table are generated according to:

if there exists some load time function with abrupt change, then time just before and just at abrupt is included in table.
between these steps under constant loads (or when load changes continuously) we use progressively increasing time step. They are best chosen so that time step be kept constant in the log (t-t') scale
Parameters

iStep Time step number.

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.

◆ requiresEquationRenumbering()

bool oofem::IncrementalLinearStatic::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.

Reimplemented from oofem::EngngModel.

Definition at line 120 of file incrementallinearstatic.h.

◆ requiresUnknownsDictionaryUpdate()

int oofem::IncrementalLinearStatic::requiresUnknownsDictionaryUpdate ( )

inlineoverridevirtual

Indicates if EngngModel requires Dofs dictionaries to be updated. If EngngModel does not support changes of static system, the dof forwards the requests for its unknowns to EngngModel, where unknowns are naturally kept. This is possible, because dof equation number is same during whole solution. But when changes of static system are allowed, several problem arise. For example by solving simple incremental static with allowed static changes, the incremental displacement vector of structure can not be added to total displacement vector of structure, because equation numbers may have changed, and one can not simply add these vector to obtain new total displacement vector, because incompatible displacement will be added. To solve this problem, unknown dictionary at dof level has been assumed. Dof then keeps its unknowns in its own private dictionary. After computing increment of solution, engngModel updates for each dof its unknowns in its dictionary (using updateUnknownsDictionary function). For aforementioned example engngModel updates incremental values but also total value by asking dof for previous total value (dof will use its dictionary, does not asks back EngngModel) adds corresponding increment and updates total value in dictionary.

◆ restoreContext()

void oofem::IncrementalLinearStatic::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 372 of file incrementallinearstatic.C.

◆ saveContext()

void oofem::IncrementalLinearStatic::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.

Reimplemented from oofem::EngngModel.

Definition at line 366 of file incrementallinearstatic.C.

◆ solveYourself()

void oofem::IncrementalLinearStatic::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 161 of file incrementallinearstatic.C.

References giveDiscreteTime().

◆ solveYourselfAt()

void oofem::IncrementalLinearStatic::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: This will eventually not be optional.
