Detailed Description

This class implements Direct Implicit Integration of Dynamic problem

Solution of this problem is series of loading cases, maintained as sequence of time-steps. This solution is in form of linear equation system \( A\cdot x = b \). The damping Matrix is assumed to be modeled as Rayleigh damping ( \( C = \eta M + \delta K \))

Initial conditions is specified at time 0.

◆ printDofOutputAt()

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

tStep	solution step

◆ restoreContext()

void oofem::DIIDynamic::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::DIIDynamic::saveContext	(	DataStream &	stream,

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.

◆ solveYourself()

void oofem::DIIDynamic::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 234 of file diidynamic.C.

◆ solveYourselfAt()

void oofem::DIIDynamic::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.

◆ updateYourself()

void oofem::DIIDynamic::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.
