Detailed Description

This class implements Adaptive Non-LinearStatic Engineering problem.

Solution of this problem is performed as a series of increments (loading or displacement). At start of Each increment we assemble new tangent stiffness, and iteratively trying to fulfill balance of external and real internal forces at end of load step (see numerical method ).

The error is estimated at the end of each load increment, and based on reached error, the computation continues, or remeshing happens. The solution is then mapped to new mesh. The solution may be taken from current state or if error is too high then is taken from previous equilibrium state.

Tasks:

• Creating Numerical method for solving nonlinear problem.
• Assembling tangent stiffness matrix
• Interfacing Numerical method to Elements
• Managing time steps

initializeFrom()

void oofem::AdaptiveNonLinearStatic::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.

restoreContext()

void oofem::AdaptiveNonLinearStatic::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.

saveContext()

void oofem::AdaptiveNonLinearStatic::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()

void oofem::AdaptiveNonLinearStatic::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.

updateDomainLinks()

void oofem::AdaptiveNonLinearStatic::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::AdaptiveNonLinearStatic::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).

timeStepLoadLevels

FloatArray oofem::AdaptiveNonLinearStatic::timeStepLoadLevels

protected

Array storing the load levels reached in corresponding time steps. It is necessary to keep track of this load level history, because after adaptive restart one has to assemble the initial and total load vectors on new mesh -> and for this it is necessary to know the history of loading. The size of this array is equal to numberOfSolutionSteps and should be stored/restored in every context file.
