The SteadyStateSubspaceStep object is used to calculate the linearized steady-state response of the system to harmonic excitation on the basis of the subspace projection method.
The SteadyStateSubspaceStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates a SteadyStateSubspaceStep object.
mdb.models[name].SteadyStateSubspaceStep
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 SteadyStateSubspaceFrequencyArray 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 ON.
A SymbolicConstant specifying how often to perform subspace projections onto the modal subspace. Possible values are ALL_FREQUENCIES, CONSTANT, EIGENFREQUENCY, PROPERTY_CHANGE, and RANGE. The default value is ALL_FREQUENCIES.
A Float specifying the maximum relative change in damping material properties before a new projection is to be performed. The default value is 0.1.
A Float specifying the maximum relative change in stiffness material properties before a new projection is to be performed. The default value is 0.1.
A Boolean specifying whether to add to the damping matrix contributions due to friction effects. The default value is OFF.
Return value
A SteadyStateSubspaceStep object.
Exceptions
RangeError.
This method modifies the SteadyStateSubspaceStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the SteadyStateSubspaceStep method, except for the name, previous, and maintainAttributes arguments.
