large flexible body

Hello,
 
I want to model a system which includes a large body that I want to model as flexible. Are there any efficient ways of doing this? I am asking because I also want to define contacts including said body, making the computations quite time consuming.
 
P.S.
 
The body is actually comprised of various smaller ones which are bolted together. Instead of creating multiple bodies and then fixing them at the bolt locations with joints, I decided to model it as a single body.
 
Thanks,

  • We're using full vehicle trimmed bodies so, yes, ADAMS can handle huge flex bodies.
     
    Best advice: Strip down your model, to debug why it's crashing.
     
    First step is usually importing the flex body into a blank model, fix it to ground with a joint and just simulate that model (plus view the modes)
    Usually people forget to deactivate the rigid body modes which makes trouble.
     
    Then use the flex body in your model, and deactivate all contacts. Maybe add some bushings to hold it in place.
    Static equilibrium will 99% fail on flex bodies with contacts.
