◆ restoreContext()

void oofem::ProblemSequence::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.

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.

inlineoverridevirtual

Shows the sparse structure of required matrix, type == 1 stiffness.

Reimplemented from oofem::EngngModel.

Definition at line 97 of file problemsequence.h.

References gc.

◆ solveYourself()

void oofem::ProblemSequence::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).

Todo: Still lacking the all important code to connect the subsequent analysis!
