Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| ACSID | Aerodynamic coordinate system identification. Default = 0 (Integer ≥ 0) |
|
| VELOCITY | Velocity for recovery of aerodynamic force data and for
calculating the reduced frequency. No default (Real > 0.0) |
|
| REFC | Reference length for reduced frequency. No default (Real > 0.0) |
|
| RHOREF | Reference density. No default (Real > 0.0) |
|
| SYMXZ | Symmetry key for the aero coordinate X-Z plane. If case
control entry AESYMXZ is specified,
this field is ignored.
|
|
| SYMXY | Symmetry key for the aero coordinate X-Y plane to simulate ground
effects. If case control entry AESYMXY
is specified, this field is ignored.

Comments
- This entry is mandatory for dynamic aeroelastic analysis. Only a single AERO entry is allowed.
- The ACSID field should reference a rectangular coordinate system. Flow is in the positive X-direction (T1).
