contextIOResultType oofem::EigenValueDynamic::restoreContext	(	DataStream &	stream,

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

mode	Determines amount of info in stream.

Returns: contextIOResultType.

Exceptions

ContextIOERR exception if error encountered.

void oofem::EigenValueDynamic::updateYourself ( TimeStep * tStep )

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).
