FEA Design Variables

Structure for the design variable tuple = ("DesignVariable Name", "Value"). "DesignVariable Name" defines the reference name for the design variable being specified. This string will be used in the FEA input directly. The "Value" must be a JSON String dictionary (see Section JSON String Dictionary).

JSON String Dictionary

If "Value" is JSON string dictionary (eg. "Value" = {"initialValue": 5.0, "upperBound": 10.0}) the following keywords ( = default values) may be used:

• initialValue = 0.0
  Initial value for the design variable.

• lowerBound = 0.0
  Lower bound for the design variable.

• upperBound = 0.0
  Upper bound for the design variable.

• maxDelta = 0.5
  Change fraction limit for the design variable.

• discreteValue = 0.0
  List of discrete values to use for the design variable (e.g. [0.0,1.0,1.5,3.0].
