Create an aerodynamic divergence subcase

  1. In the Simulation Navigator, right-click the static aeroelastic response solution node and choose New Subcase.The Solution Step dialog box opens.

  2. In the Solution Step dialog box, from the Step list, select Subcase - Aeroelastic Divergence.

  3. Click Create Step.The Properties, Aerodynamic Symmetry, and Boundary Condition Control Variables groups appear.

  4. Click OK.
