Hi All,

I am having some difficulty with interval outputs using NODOUT. My simulation time is 0.125 seconds and I requested output results for every 1.25e-3 seconds. However, Ls Prepost does not report the results at exactly 1.25e-3 time interval. It only provides an approximate interval of 1.22e-3 seconds. Is there a fix for this kind of problem?

Thanks

Hi @kingoz79, 

Have you also defined *Database_binary_d3plot with dt=1.25e-3? I'm not sure why LS-Dyna wouldn't be giving your outputs at the frequency you requested. Can you also double check that your termination time is 0.125 seconds and not 0.122 seconds?

@negativevolume I have checked and my time-step (1.25e-3) is consistent with sufficient increments (100) to reach the exact termination time of 0.125. However, the output time interval reported by Ls Prepost is still not correct.
