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.
No default (Integer ≥ 0 or blank) |
|
NINT | Number of interference elements.
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
- Point 1 is the leading point of the body.
- All CAERO1 (panels) and CAERO2 (bodies) in the same IGID (group) have aerodynamic interaction.
- At least one interference element is required for the aerodynamic body specified by this entry.
- 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.
- At least two slender body elements are required for each aerodynamic body.
- Interference elements are only intended for use with panels.
