Structure for the design variable tuple = ("DesignVariableRelation Name", "Value"). "DesignVariableRelation 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" = {"componentType": "Property", "componentName": "plate", "variableName": "MyDesVar"}) the following keywords ( = default values) may be used:

componentType = "Property"
The type of component for this design variable relation. Options: "Property".

componentName = "(no default)"
Single FEA Property linked to the design variable (e.g. "Name1").
- For componentType Property a FEA Property name (or names) is given.

variableName = "(no default)"
Name of design variable linked to this relation

constantCoeff = 0.0
Constant term of relation.

linearCoeff = 1.0
Single or list of coefficients of linear relation. Must be same length as variableName.
