Hi,

I have to set up a transient analysis using this plot of acceleration in function of period like input (in Optistruct). I don't know how i can do it. Could you help me, please?

    Thank you very much. I understand the process step.

    I'm wondering if it is correct to put in TABLEDi the data number of the plot above (so put in directly acceleration - period or frequency). Is the card TABLED acceleration - time or not? If i can't put in the TABLED the period what can i do?

    Hi @Tachs77

     

    Since you are asking about transient analysis, the table should contain load vs time data and not frequency.

     

    You can set the type of load in TLOAD card, say acceleration for example.
