Hi All,

I am Running a Frontal crash  Analysis.

Will AMS suit for this. The time step is not reaching the target value. But the energy error is increasing from the beginning.

 

Need Hellp.

 

Regards,

SUBHU

    Hi Subhu,

    AMS is not recommended for crash analysis. The conventional mass scaling, that is /DT/NODA/CST (mass error preferably less than 2 percent) is advisable for crash simulations where as AMS is recommended for quasi static simulations, where the velocity is low and the kinetic energy is very small and in such cases the effect is insignificant or negligible.
