CFD Design Variable

Structure for the design variable tuple = ("DesignVariable Name", "Value"). "DesignVariable Name" defines the reference name for the design variable being specified. The "Value" may be a JSON String dictionary (see Section JSON String Dictionary) or just a blank string (see Section Single Value String).

Note that any JSON string inputs are written to the input files as information only. They are only use if the analysis is executed with the analysis specific design framework.

JSON String Dictionary

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

• lowerBound = 0.0 or [0.0, 0.0,...]
  Lower bound for the design variable.

• upperBound = 0.0 or [0.0, 0.0,...]
  Upper bound for the design variable.

• typicalSize = 0.0 or [0.0, 0.0,...]
  Typical size for the design variable.

Single Value String

If "Value" is a string, the string value will be ignored.
