Hi pnomura,
Generally, in a case like this, you would want to give your dropped object an initial (calculated) velocity and move the object to within close proximity of the surface to be impacted. That will ensure that the contact search algorithm has a good chance of finding the contact geometry.
Hi Mrkvel,
I've submitted several CLA packages using pyYeti, but most of the work is done in pandas.
My submittals consist of:
1. An Excel file with the LTM, ATM, & DTM.
2. The partitioned op4 file that contains stiffness and mass matrices as well as acceleration, displacement, and loads...
Sorry, I think I misinterpreted your original post, that said, wrt item 1, typically if the aeroelastic analysis is not done internally within NASTRAN then the generalized stiffness/mass/damping matrices are taken from NASTRAN and processed externally. If you want NASTRAN to do that and if you...
Hi Spyros07,
Your best approach would be to skip the DMAP alters and use NASTRAN CMS (ie, superelement). You'll probably want a reduced model anyway for aeroelastic's. I'm pointing you in a different direction here, and it's not that you can't use DMAP, it just wouldn't be what I would call best...
