The following lists the input for the Executive Control Section of the ZAero input file

FEM JSON String Dictionary

FEM input must be a JSON string dictionary (e.g. {"boundary": "sym", "suport": [1,3], "print": 1} where the following keywords ( = default values) may be used:

• fem = ""
  Optional Absolute file path to f06 file from a structural analysis. Cannot be specified if F06 is linked.

• form = ""
  Optional string describing solver used to generate FEM file. If "fem" is specified then "form" must be one of:
  'MSC' generated by MSC.NASTRAN or NX.NASTRAN 'NE' generated by NE/NASTRAN 'ASTROS' generated by ASTROS 'IDEAS' generated by I-DEAS 'ELFINI' generated by ELFINI 'GENESIS' generated by GENESIS 'ABAQUS' generated by ABAQUS 'ALTAIR' generated by ALTAIR's RADIOSS 'FREE ' stored according to the input instruction described in Remark 9 of ZAero manual

• boundary = "SYM"
  "boundary" indicates the boundary condition of the structural finite element model.
  'SYM' for symmetric boundary condition
  'ANTI' for anti-symmetric boundary condition
  'ASYM' for asymmetric boundary condition
  

• support = [0, 0]
  "support" up to length 2 array for the m/L ZAero support input. See ZAero manual for details.

• print = 0
  Print options to the standard output file; where n is an integer.
  n = 0 \t no printout of the imported structural free vibration solution.
  | n | >= 1 \t print out the structural grid point locations in the aerodynamic coordinate system.
  n >= 2 \t print out the modal data (mode shapes) at the structural grid points in the aerodynamic coordinate system.
  n <= -2 \t print out the interpolated modal data at the control points of the aerodynamic boxes in the aerodynamic coordinate system.
  n = 3 \t print all of the above
