Dv

Model ElementDv defines a special type of solver state variable. It is used in the evaluation and computation of design sensitivity as a design parameter. Its value is modified during the simulation in case of Design Sensitivity Analysis.

Attribute Summary

Name	Property	Modifiable by command?
id	Int ()
label	String ()
b	DvDouble (required=True)
blimit	Double (count=2)

Usage

Dv (b=initialValues, optional_attributes)

Attributes

b: Double(); Specifies the initial value of design variable.; The b attribute is mandatory.
blimit: List of two numbers.; Specifies the upper and lower bound of design variable. The value of design variable b is subjected to vary in the range: blimit[0]≤ b ≤ blimit[1].; This attribute is optional. When not specified, the design variable can be an arbitrary real number.
id: Integer.; Specifies the element identification number. This number must be unique among all the Dv objects in the model.; This attribute is optional. MotionSolve automatically creates an ID when one is not specified.; Range of values: id > 0.
label: String; Specifies the name of the Dv object.; This attribute is optional. When not specified, MotionSolve creates a label for you.

Example

This example shows a simple definition of a design variable.

Dv(b=10)
