Aeroelasticity, as the name implies, is the coupling of aerodynamics and structures. Prior to performing an aeroelastic analysis with MSC.FlightLoads and Dynamics, an aeroelastic model must be identified. This model is comprised of a structures model (of necessity, one that is appropriate for dynamics analysis -- it should include appropriate inertias and produce good normal modes), an aerodynamic model, and the splines that couple the two models. FlightLoads was designed to support the evolution (maturation) of aero and structural models. Multiple representations of the structure and the aerodynamic meshes may appear in a single database for subsequent use in aeroelastic analyses. It is also appropriate at this point in the simulation process to define the model-dependent parameter data pertaining to structural and aerodynamic model behaviors.

Following is a list of the Aeroelastic Model form and its subforms:

This subform is used to identify the aerodynamic component of the aeroelastic model. The selected aero model must be a SuperGroup. The current SuperGroup is the default selection. An alternative SuperGroup may also be selected.

This subform is used to select the structural component of the aeroelastic model. As in standard structural analyses from MSC.Patran, users can select all structural elements in the database or a specific Group. The default selection is "Entire Model".

Model Parameters allows the user to change the default model behavior and representation in MSC.Nastran.

This form is used to define the basic properties for static aeroelasticity.

These forms are subforms for Global Data provided as a convenience to users. Length and area calculations are performed based on selection of points from the graphics viewport.
