9.5 AccelerationBCState object

The AccelerationBCState object stores the propagating data of an acceleration boundary condition in a step. One instance of this object is created internally by the AccelerationBC object for each step. The instance is also deleted internally by the AccelerationBC object.

The AccelerationBCState object has no constructor or methods.

The AccelerationBCState object is derived from the BoundaryConditionState object.

amplitudeState

A SymbolicConstant specifying the propagation state of the amplitude reference. Possible values are UNSET, SET, UNCHANGED, FREED, and MODIFIED.

status

A SymbolicConstant specifying the propagation state of the BoundaryConditionState object. Possible values are:

  • NOT_YET_ACTIVE

  • CREATED

  • PROPAGATED
