Recommended Posts

Hi,

 

the following might help you:

First try to set up the simulation yourself, because you will not learn if someone else did it for you. Besides, not enough details are provided like material and initial velocity.

I have set up impact attenuator simulation however, material (aluminium), initial velocity (10000mm/s) and impactor mass (1 tonne) were defined arbitrarily, so you may want to change those to suit your specifications. Advanced mass scaling is defined to speed up computation, but in the final run you may want to turn it off and use traditional mass scaling dt/noda/cst instead. Ishell flag can be set to 24 on shelldefault control card to avoid hourglassing.
