Hello Daniel,

Yes, you can simulate longer events than 1 second with explicit dynamics. The limit of 1second is a general guideline, but if you have the computer power, you can certainly simulate longer than 1 seconds with explicit dynamics (LS-DYNA). In our training, we have the following slide:

We have customers simulating events up to 30-40 seconds with LS-DYNA explicit dynamics.

 

I don't understand when you say "I have to compare the ls dyna results with the explicit dynamic results.". LS-DYNA is an explicit dynamics code. You have results from another explicit dynamics code (or solver) and you want to compare these results with LS-DYNA?

You say the simulation is not working. What do you mean by it is not working? Do you get an error message? The results are not what you are expecting? Do you have experimental results to compare? 

 

Reno.
