Detailed Description

Class representing solution step.

The timeStep instance may represent either time step, load increment, or load case depending on used Engineering model. See corresponding EngngModel reference for details. TimeStep maintains a reference to corresponding Engineering model class instance.

The class hold target time, which may represent the end of time interval. In addition, there is intrinsic time, which is normally set the same as target time. Intrinsic (assembly) time is used especially in constitutive laws, where the material law is not meant to be evaluated at target time. Also, imposing boundary conditions occurs at intrinsic time by default. This reflects changes of static system and proper equation numbering during each timeStep.

Some components (typically integration points real stresses or integration points nonlocal values) are computationally very demanding. Because in typical code, there are number of requests for same value during the computation process, it may be efficient to store these values and compute them only once. The principal problem is to recognize, when is necessary to re-compute these stored values to reflect newly reached state. This cannot be determined form solution step "time", because solution step may represent for example load increment, inside which typically many iterations are needed to reach convergence. For this purpose, a concept of solution state counters is provided. Whenever the solution state changes, the engineering model updates the solution state counter. The solution state counter is guaranteed to grow up smoothly (it newer decreases) during solution process. Other components of program (integration points) can then store their computationally expensive values but have to store also corresponding solution state counter value valid when these were computed. Then, easy check is done for finding differences between frozen solution state counter and their value with current solution state requested from solution step and recompute the values if necessary.

contextIOResultType oofem::TimeStep::saveContext	(	DataStream &	stream,
		ContextMode	mode,

Stores receiver state to output stream.

Receiver should write class-id first in order to allow test whether correct data are then restored.

Parameters

stream	Output stream.
mode	Determines amount of info required in stream (state, definition,...).
obj	Special parameter, used only to send particular integration. point to material class version of this method. Except this case, obj parameter is always NULL pointer.

Exceptions

ContextIOERR
