Modeling Object
Name Specifies a descriptive name for this modeling object.
Label Specifies a unique numerical identifier for this modeling object.
Properties
Description Lets you enter a brief description. Click to open a text editor where you can enter a longer description.
Preview Relationship Displays the constraint equation that relates the independent variables and the dependent variable.
Dependent Variable
Dependent Variable lists Specifies the dependent variable in the constraint relation.Standard VariableUse to specify a standard static aeroelastic trim variable as the dependent variable.Select an existing standard static aeroelastic trim variable modeling object from the second Dependent Variable list.User VariableUse to specify a user-defined static aeroelastic trim variable as the dependent variable.Select an existing user-defined static aeroelastic trim variable modeling object from the second Dependent Variable list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.To filter a long list of modeling objects, click More Options to display options for searching and filtering the modeling objects.For more information, see Filter options.Control Surface VariableUse to specify a aerodynamic control surface variable as the dependent variable.Select an existing aerodynamic control surface variable from the second Dependent Variable list or click Create Aerodynamic Control Surface to create a new one.Click Variable to select an aerodynamic control surface variable from the graphics window or from the Simulation Navigator.Click Edit to edit the selected aerodynamic control surface variable.To filter a long list of aerodynamic control surface variables, click More Options to display options for searching and filtering the modeling objects.For more information, see Filter options.
Standard Variables
**Angle of Attack - R2 (ANGLEA)****Angle of Sideslip - R3 (SIDES)****Roll Rate - R1 (ROLL)****Pitch Rate - R2 (PITCH)****Yaw Rate - R3 (YAW)****Longitudinal - T1 (URDD1)****Lateral Acceleration - T2 (URDD2)****Vertical Acceleration - T3 (URDD3)****Roll Acceleration - R1 (URDD4)****Pitch Acceleration - R2 (URDD5)**Yaw Acceleration - R3 (URDD6) Specifies the numerical linking coefficients that the software uses to form the constraint relation as a linear combination of the dependent variable and the independent static aeroelastic trim variables.
User Variables
Variable 1 through Variable 10 Specifies the numerical linking coefficients that the software uses to form the constraint relation as a linear combination of the dependent variable and the independent user-defined static aeroelastic trim variables.Select an existing user-defined static aeroelastic trim variable modeling object from the list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.To filter a long list of modeling objects, click More Options to display options for searching and filtering the modeling objects.For more information, see Filter options.Specify the numerical linking coefficient for a user-defined static aeroelastic trim variable in the Linking Coefficients of Independent Variables box.
