The SubspaceDynamicsStep 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 SubspaceDynamicsStep object is derived from the AnalysisStep object.
import step mdb.models[name].steps[name]
This method creates a SubspaceDynamicsStep object.
mdb.models[name].SubspaceDynamicsStep
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.
Optional arguments
A String specifying a description of the new step. The default value is an empty string.
A Float specifying the total time period of the step. The default value is 1.0.
The SymbolicConstant ALL or an Int specifying the number of modes to be used for subspace projection. The possible value for the SymbolicConstant is ALL. The default value is ALL.
A Boolean specifying whether to allow for geometric nonlinearity. The default value is OFF.
An Int specifying the maximum number of increments in a step. The default value is 100.
A Float specifying the suggested time increment. The default value is 0.0.
A SymbolicConstant specifying the amplitude variation for loading magnitudes during the step. Possible values are STEP and RAMP. The default value is STEP.
A Boolean specifying whether to retain attributes from an existing step with the same name. The default value is False.
Return value
A SubspaceDynamicsStep object.
Exceptions
RangeError.
This method modifies the SubspaceDynamicsStep object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the SubspaceDynamicsStep method, except for the name, previous, and maintainAttributes arguments.
