FEA Design Equation Responses

Structure for the design equation response tuple = ("DesignEquationResponse Name", "Value"). "DesignEquationResponse Name" defines the reference name for the design equation response 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). In Nastran the DesignEquationResponse Name will be the LABEL used in the DRESP2 input. For this reason the user should keep the length of this input to a minimum number of characters, ideally 7 or less.

JSON String Dictionary

If "Value" is JSON string dictionary (eg. "Value" = {"equation": "EQ1", "constant": ["PI", "YM", "L"]}) the following keywords ( = default values) may be used:

• equation
  The name of the equation referenced by this equation response.

• variable = "(no default)"
  Single or list of names of design variable equation parameters.

• constant = "(no default)"
  Single or list of names of table constant equation parameters.

• response = "(no default)"
  Single or list of names of design response equation parameters.

• equationResponse = "(no default)"
  Single or list of names of design equation response equation parameters.
