Definitions

Field Contents SI Unit Example
EID Unique element identification number.

No default (Integer > 0)

PID Identification number of a PAERO2 property entry.

No default (Integer > 0)

CP Coordinate system for locating points 1 and 4.

Default = 0 (Integer ≥ 0)

NSB Number of slender body elements.
> 0
NSB equal divisions are assumed.
0 or blank
List of divisions is specified in LSB.

No default (Integer ≥ 0 or blank)

NINT Number of interference elements.
> 0
NINT equal divisions are assumed.
0 or blank
List of divisions is specified in LINT.

No default (Integer ≥ 0 or blank)

LSB ID of an AEFACT Bulk Data Entry for slender body division points; this is used only if NSB is zero or blank.

Default = blank (Integer ≥ 0)

LINT ID of an AEFACT Bulk Data Entry containing a list of division points for interference elements; this is used only if NINT is zero or blank.

Default = blank (Integer ≥ 0)

IGID Interference group identification. Aerodynamic elements with different IGIDs are uncoupled.

(Integer > 0)

X1, Y1, Z1 Location of point 1 in coordinate system CP.

(Real)

X12 Length of body in the x-direction of the aerodynamic coordinate system.

(Real > 0)

Comments

  1. Point 1 is the leading point of the body.
  2. All CAERO1 (panels) and CAERO2 (bodies) in the same IGID (group) have aerodynamic interaction.
  3. At least one interference element is required for the aerodynamic body specified by this entry.
  4. The beams and connection points are numbered sequentially beginning with EID. Ensure that all aero elements and connection point IDs are unique. Overlapping IDs between structure and aerodynamic models are allowed, but affect the result visualization.
  5. At least two slender body elements are required for each aerodynamic body.
  6. Interference elements are only intended for use with panels.
