Generalized Aerodynamic Force Matrix extraction
Generalized Aerodynamic Force Matrix extraction
(OP)
Hello all,
Anyone knows how to extract the Generalized Aerodynamic Force matrix (QHH) of flexible modes from the nastran database? I am currently doing a SOL 145
Thank you,
Jose Daniel

Be careful with the above output; I am not completely sure if QHHL is the right output for you; you may need to do some manipulation. If the terms of QHHL do not look like the numbers you are expecting, try browsing the content of the MSC Nastran Aeroelastic forum of the MSC Software VPD forum, at http://forums.mscsoftware.com/news/ubbthreads.php. Others have requested this output in the past. If you don't see what you need over there, you can always post a request to that forum; there are MSC staff as well as clients who participate in the forums.

Whenever I have a solution I will post it here for future forum users.
The code line I'll be using first is (to make it easy for future forum users):
COMPILE SUBDMAP=FLUTTER,SOUIN=MSCSOU,NOREF,NOLIST $ V3
ALTER 50 $ V3
MATPRN QHHL// $ PRINTS QHHL MATRIX
EXIT $
