25.10 CavityRadiationState object

The CavityRadiationState object stores the propagating data for a CavityRadiation object. One instance of this object is created internally by the CavityRadiation object for each step. The instance is also deleted internally by the CavityRadiation object.

The CavityRadiationState object has no constructor or methods.

The CavityRadiationState object is derived from the InteractionState object.

25.10.1  Members

The CavityRadiationState object has the following members:

blocking

A SymbolicConstant specifying the blocking checks to be performed in the viewfactor calculations. Possible values are BLOCKING_ALL, NO_BLOCKING, and PARTIAL_BLOCKING.

blockingState

A SymbolicConstant specifying the propagation state of the blocking member. Possible values are UNSET, SET, UNCHANGED, and FREED.

blockingSurfacesState

A SymbolicConstant specifying the propagation state of the blockingSurfaces member. Possible values are UNSET, SET, UNCHANGED, and FREED.

rangeOfView

A Float specifying the distance beyond which factors need not be calculated because surfaces are judged to be too far apart to “see” each other (due to blocking by other surfaces).

rangeOfViewState

A SymbolicConstant specifying the propagation state of the rangeOfView member. Possible values are UNSET, SET, UNCHANGED, and FREED.

surfaceReflection

A Boolean specifying whether reflection must be included in the cavity radiation calculations. The default value is ON.

surfaceReflectionState

A SymbolicConstant specifying the propagation state of the surfaceReflection member. Possible values are UNSET, SET, UNCHANGED, and FREED.

viewfactorAccuracyTol

A Float specifying the acceptable tolerance for the viewfactor calculations.

viewfactorAccuracyTolState

A SymbolicConstant specifying the propagation state of the viewfactorAccuracyTol member. Possible values are UNSET, SET, UNCHANGED, and FREED.

blockingSurfaces

A tuple of Strings specifying the surfaces that provide blocking inside the cavity.

status

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

  • BUILT_INTO_BASE_STATE
