Wave Response steady state solution plots

Hi there,

I have created a rather large model and am interested in the steady state displacement of this model under four wave cases.

To this end I have created a SACS input file for the structural model, a Seastate file for the environmental loading and extracted the first 100 mode shapes and created a dynamic mass file using Dynpac.

After this I use the Wave Response program to determine the steady state displacement x-, y- and z-direction for multiple joints.

However, when running the wave response program I am limited by the 66 character length of the PSJO line - I am interested in the x, y and z displacement of about 44 joints at the minimum.

1. Is there any way to select more joints to have their data plotted / output?

2. Is there any option to visualize the steady state response of the entire model?

I have tried adding multiple PSJO lines, this did not produce more data.

I hope to hear from you.

  • Hi Eduard,

    1. Currently SACS only support single PSJO line for joint displacement plot, but you can output all joints displacement in test format. In wave response analysis option definition, choose to generate a postvue database. Open this Psvdb file in precede, use file-generate report - joint displacement and include joints you're interested. Then you can get the joints displacement from wave response.

    2. Yes, you can also check the global structure deflection under wave response using postvue database. Open it in precede and choose "deflection shape option", you can have visualization of the structure deflection under wave response load case.
