The SteadyStateDirectStep object is used to calculate the linearized steady-state response of the system to harmonic excitation in terms of the physical degrees of freedom of the model.
The SteadyStateDirectStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates a SteadyStateDirectStep object.
mdb.models[name].SteadyStateDirectStep
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 SteadyStateDirectFrequencyArray object.
Optional arguments
A String specifying a description of the new step. The default value is an empty string.
A SymbolicConstant specifying whether damping terms are to be ignored so that a real, rather than a complex, system matrix is factored. Possible values are REAL_ONLY and COMPLEX. The default value is COMPLEX.
A SymbolicConstant specifying whether a logarithmic or linear scale is used for output. Possible values are LOGARITHMIC and LINEAR. The default value is LOGARITHMIC.
A SymbolicConstant specifying the type of matrix storage. Possible values are SYMMETRIC, UNSYMMETRIC, and SOLVER_DEFAULT. The default value is SOLVER_DEFAULT.
A Boolean specifying whether to retain attributes from an existing step with the same name. The default value is False.
A Boolean specifying whether to subdivide each frequency range using the eigenfrequencies of the system. The default value is OFF.
A Boolean specifying whether to add to the damping matrix contributions due to friction effects. The default value is OFF.
Return value
A SteadyStateDirectStep object.
Exceptions
RangeError.
This method modifies the SteadyStateDirectStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the SteadyStateDirectStep method, except for the name, previous, and maintainAttributes arguments.
