Detailed Description

Implementation of general sequence (staggered) problem.

The problem consists in sequence of low level problems (slaves) which are executed sequentially and where the results of particular slave depends on the results of previous slaves in sequence. Typical example is heat&mass transfer analysis followed by mechanical one, which takes into account the temperature field from the first analysis.

The sequence problem is represented by this class. It maintains list of subsequent (slave) problems and it is executes the slave problems. It is responsible for solution step generation and synchronization between slave problems. The transfer of required state variables is done by mapping of corresponding variables between problem domains. This allows to to transfer primary (nodal) values of one problem to integration points of subsequent problem or to use completely different discretizations for slave problems.

Since the master problem is responsible for synchronization, it is responsible for generation the solution steps. Therefore, the solution step specification, as well as relevant meta step attributes are specified at master level.

Note: To avoid confusion, the slaves are treated in so-called maintained mode. In this mode, the attributes and meta step attributes are taken from the master. The local attributes, even if specified, are ignored.

Forces equation renumbering on all domains associated to engng model.

All equation numbers in all domains for all dofManagers are invalidated, and new equation numbers are generated starting from 1 on each domain. It will update numberOfEquations variable accordingly. Should be used at startup to force equation numbering and therefore sets numberOfEquations. Must be used if model supports changes of static system to assign new valid equation numbers to dofManagers.

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

void oofem::StaggeredProblem::printYourself ( )

contextIOResultType oofem::StaggeredProblem::restoreContext	(	DataStream &	stream,
		ContextMode	mode
	)

virtual

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.

Returns: contextIOResultType.

Exceptions

ContextIOERR exception if error encountered.

void oofem::StaggeredProblem::solveYourself ( )

void oofem::StaggeredProblem::updateAttributes ( MetaStep * mStep )

virtual

Update receiver attributes according to step metaStep attributes.

Allows the certain parameters or attributes to be updated for particular metastep. The metastep provides the attributes record, from which the corresponding attributes can be read. The service takes a MetaStep parameter. It is recommended, to implement this service in such way, that multiple calls for steps belonging to same MetaStep does not change response. The default implementation updates the numerical method attributes.

Parameters

mStep Meta step.
