APD
Generates aerodynamic geometry tables
Parameters:
NK Output-integer-no default. Number of degrees of freedom in the
k displacement set.
NJ Output-integer-no default. Number of degrees of freedom in the j
displacement set.
BOV Output-integer-default=0.0. Value calculated by REFC/(2.*VELOCITY).
AERTYP Input-character-default='DYNAMICS'.
Analysis type:
'STATICS' – aerostatic
'DYNAMICS' – flutter and aeroelastic
'STADYN' – all aerodynamic analysis types
BOXIDF Output-integer-default. Box corner point identification flag.
Remarks:
1. AEECT*, AEBGPDT*, and AEUSET* are output family data blocks based on
qualifiers AEID and MODLTYPE. AEID is not currently being used and is
always 0.
2. BGPDT, ECT, and USET0 where MODLTYPE='STRUCTUR' are output by GP1,
GP2, and GP4, respectively.
Example:
0 Points have unique identification numbers starting with the
aerodynamic component identification number.
-1 Points identification numbers are incremented by 1, to avoid an
overlap if they were started with the aerodynamic component
identification numbers. No display of the corner points is possible.
MODLTYPE Model DOF set
STRUCTUR structural p-set
AEROSTRC aero-structural ks-set
AEROMESH plotting n/a
The first statement sets the MODLTYPE qualifier for data blocks BGPDTS and USET.
The subsequent DBVIEW statements reference the outputs from APD for use in other
modules.
