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.
= -1
For anti-symmetry
= 0 (Default)
For no symmetry
= 1
For symmetry
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.
= -1
For symmetry
= 0 (Default)
For no symmetry
= 1
For anti-symmetry

Comments

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