The RandomResponseStep object is used to give the linearized response of a model to random excitation.
The RandomResponseStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates a RandomResponseStep object.
mdb.models[name].RandomResponseStep
Required arguments
A String specifying the repository key.
A String specifying the name of the previous step. The new step appears after this step in the list of analysis steps.
A RandomResponseFrequencyArray object specifying frequencies over ranges of modes.
Optional arguments
A String specifying a description of the new step. The default value is an empty string.
A SymbolicConstant specifying the frequency scale. Possible values are LINEAR and LOG. The default value is LOG.
A DirectDamping object.
A CompositeDamping object.
A RayleighDamping object.
A StructuralDamping object.
A DirectDampingByFrequency object.
A RayleighDampingByFrequency object.
A StructuralDampingByFrequency object.
A Boolean specifying whether to retain attributes from an existing step with the same name. The default value is False.
Return value
A RandomResponseStep object.
Exceptions
RangeError.
This method modifies the RandomResponseStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the RandomResponseStep method, except for the name, previous, and maintainAttributes arguments.
Return value
Exceptions
RangeError.
