Define aerodynamic divergence data

  1. Choose Home tab→Properties group→Modeling Objects .The Modeling Object Manager dialog box opens.

  2. In the Modeling Objects Manager dialog box, from the Type list, select Aerodynamic Divergence Data and click Create.The Aerodynamic Divergence Data dialog box opens.

  3. In the Aerodynamic Divergence Data dialog box, in the Number of Roots box, type the number of divergence roots to output.

  4. In the Mach number box, type the Mach numbers to include in the set.To include multiple values, use a space between each value.

  5. Click OK.

  6. In the Modeling Objects Manager dialog box, click Close.
