SpectrumAmplitude(...)
This method creates a SpectrumAmplitude object.
Path
mdb.models[name].SpectrumAmplitude session.odbs[name].SpectrumAmplitude
Required arguments
- name
-
A String specifying the repository key.
- method
-
A SymbolicConstant specifying the method for specifying the spectrum. Possible values are DEFINE and CALCULATE.
- data
-
A sequence of sequences of Floats specifying the magnitude, frequency, and damping values.
Optional arguments
- specificationUnits
-
A SymbolicConstant specifying the units used for specifying the spectrum. Possible values are DISPLACEMENT, VELOCITY, ACCELERATION, and GRAVITY. The default value is ACCELERATION.
- eventUnits
-
A SymbolicConstant specifying the units used to describe the dynamic event in the amplitude used for the calculation. Possible values are EVENT_DISPLACEMENT, EVENT_VELOCITY, EVENT_ACCELERATION, and EVENT_GRAVITY. The default value is EVENT_ACCELERATION.
- solution
-
A SymbolicConstant specifying the solution method for the dynamic equations. Possible values are ABSOLUTE_VALUE and RELATIVE_VALUE. The default value is ABSOLUTE_VALUE.
- timeIncrement
-
A Float specifying the implicit time increment used to calculate the spectrum. This argument is required when the method = CALCULATE. The default value is 0.0.
- gravity
-
A Float specifying the acceleration due to gravity. This argument applies only when specificationUnits = GRAVITY oreventUnits = GRAVITY. The default value is 1.0.
- criticalDamping
-
A Boolean specifying whether to calculate the spectrum for only the specified range of critical damping values or a list of values. If criticalDamping = ON, the spectrum is calculated only for the specified range of critical damping values. If criticalDamping = OFF, the spectrum is calculated for a list of damping values. The default value is OFF.
- timeSpan
-
A SymbolicConstant specifying the time span of the amplitude. Possible values are STEP and TOTAL. The default value is STEP.
- amplitude
-
A String specifying the name of the amplitude that describes the dynamic event used to calculate the spectrum. The default value is an empty string.
Return value
A SpectrumAmplitude object.
Exceptions
InvalidNameError and RangeError.
