Hi,
I am trying to building a 2D Structural Mechanics model on an airbag that is used to serve as a damping mattress for an object falling on it. The airbag is assumed to have a round intersection, cylinder in shape 3D wise, with air in it. It seems the round shape airbag cannot have a solution. The error shows:
Error:
Failed to find a solution:
No convergence, even when using the minimum damping factor.
Returned solution has not converged.

I tried some other shape which is not perfectly round, it works. So I hope to know how should I model the round shape airbag?
Thanks!
Kevin
