The PressurePenetrationState object stores the propagating data of a PressurePenetration object in a step. One instance of this object is created internally by the PressurePenetration object for each step. The instance is also deleted internally by the PressurePenetration object.
The PressurePenetrationState object has no constructor or methods.
The PressurePenetrationState object is derived from the InteractionState object.

The PressurePenetrationState object has the following members:
A Float specifying the fraction of the current step time over which the fluid pressure on newly penetrated contact surface segments is ramped up to the current magnitude. The default value is 10–3.
A SymbolicConstant specifying the propagation state of the penetrationTime member. Possible values are UNSET, SET, UNCHANGED, and FREED.
A SymbolicConstant specifying the propagation state of the amplitude member. Possible values are UNSET, SET, UNCHANGED, and FREED.
A SymbolicConstant specifying the propagation state of the criticalPressure member. Possible values are UNSET, SET, UNCHANGED, and FREED.
A SymbolicConstant specifying the propagation state of the penetrationPressure member. Possible values are UNSET, SET, UNCHANGED, and FREED.
A tuple of Floats specifying the fluid pressure magnitude. For steady state dynamic analyses, a tuple of Complexes specifying the fluid pressure magnitude.
A String specifying the name of the amplitude reference. The String is empty if the load has no amplitude reference.
A tuple of Floats specifying the critical contact pressure below which fluid penetration starts to occur.
A SymbolicConstant specifying the propagation state of the InteractionState object. Possible values are:
NOT_YET_ACTIVE
CREATED
PROPAGATED
MODIFIED
DEACTIVATED
NO_LONGER_ACTIVE
TYPE_NOT_APPLICABLE
INSTANCE_NOT_APPLICABLE
