Results in Frequency domain (Impact loads)

Dear All,

I am trying to model impact loads on a steel structure. But I am wandering how I can get the results in the frequency domain?
It automatically shows results in the time domain...
Thank you in advance!!

  • Are you performing a ship impact or dropped object analysis using SACS? This forum is for MAXSURF, MOSES and SACS so it helps if we know which program you are using. The SACS impact analyses are exclusively time-domain analyses. There isn't really a frequency-domain since the loading isn't cyclical. Do you mean the modal responses? You can plot the modal responses vs time with the PLT option on the THLOAD line. See section 2.6 of the dynamic response manual for more details.

    Regards,
