How to apply static structure after ls dyna analysis for collisioned model?

 

[Andreas Koutras]

Hello, do you mean how to perform a static analysis after an explicit analysis?

To switch from explicit to implicit, the option IMFLAG<0 of CONTROL_IMPLICIT_GENERAL can be used. However, it may be challenging for the implicit analysis to converge depending on the level of prior damage and various analysis settings. Applying the load quasi-statically using explicit analysis will be more promising

Hello, thanks for ur replay. Unfortunately, I don't get the point, can you give more explanation?

Hello Mahmoud, 

Andreas is suggesting to apply the static loads in the LS-Dyna solver at the end of the collision event and not use the Static Structural solver.

Please explain what type of static load you want to apply to the model after a collision event. Show an image if possible.
