Properties

Defining properties

The following properties are defined on the class

Name Type Description Quantity
Frequency double - Frequency [Hz]
MassX double Total modal mass in the X-direction for eigenvector normalisation. Mass [kg]
MassY double Total modal mass in the Y-direction for eigenvector normalisation. Mass [kg]
MassZ double Total modal mass in the Z-direction for eigenvector normalisation. Mass [kg]
RotationalMassX double Total modal mass for rotation about the X-axis for eigenvector normalisation. Mass [kg]
RotationalMassY double Total modal mass for rotation about the X-axis for eigenvector normalisation. Mass [kg]
RotationalMassZ double Total modal mass for rotation about the X-axis for eigenvector normalisation. Mass [kg]

Inherited properties

The following properties are inherited from the base class of the object

Name Type Description Quantity
ObjectId IComparable Id of the structure. Unused for many results. -
ResultCase IComparable Identifier for the Loadcase or LoadCombination that the result belongs to. Is generally name or number of the loadcase, depending on the analysis package. -
ModeNumber int Positive index, starting at one. Only set for cases with modal outputs such as dynamic cases. -
TimeStep double Time step for time history results. -

Derived properties

The following properties are defined as extension methods in one of the BHoM_Engines

Name Type Description Quantity Engine
AllIdentifierProperties List<string> Gets the name of all properties of the result that are of identifier types. This is all properties tagged with any IdentifierAttribute. - Results_Engine
ObjectIdentifierProperties List<string> Gets the name of all properties of the result that are of ObjectIdentifier types. This is all properties tagged with the ObjectIdentifierAttribute. - Results_Engine
ResultPropertyKeys List<string> Returns the result value carrying properties available for the result type provided. Currently only supported for IResultItem and IResultCollection<IResultItem> type results. - Results_Engine
ScenarioIdentifierProperties List<string> Gets the name of all properties of the result that are of Scenario types. This is all properties tagged with the ScenarioIdentifierAttribute. - Results_Engine
