AESYMXY

I/O Options and Subcase Information Entry Aerodynamic XY plane of symmetry flag. The AESYMXY command can be used in the case control section to indicate whether the aerodynamic model has symmetry with respect to the ground.

Format

AESYMXY = option

Definitions

Argument Options Description
option <SYMMETRIC, ANTISYMMETRIC, ASYMMETRIC>

Default: See Comments
SYMMETRIC
Indicates that the aerodynamic model is moving in a symmetric manner with respect to the XY plane.
Implies ground effect.
ANTISYMMETRIC
Indicates that the aerodynamic model is moving in an antisymmetric manner with respect to the XY plane.
ASYMMETRIC:
Indicates that the aerodynamic model has no reflection about the XY plane.
Implies free air analysis.

Comments

  1. If AESYMXY is not present in case control, aerodynamic XY symmetry will be determined from the SYMXY field of the AEROS Bulk Data Entry for static aeroelastic analysis.
  2. If AESYMXY is present above the subcase level, it is applied to all subcases until overridden.
