Random base excitation results

The following table lists the output requests that you can enable in the Random Output Requests modeling object and the corresponding post-processing results nodes.

Warning:

In post-processing, the software automatically computes and displays derived quantities for certain results types. For the peak and number of positive crossing random results, ignore these derived quantities as they are inaccurate. For more information, see Accurate and derived peak results.

Note:

The elemental-nodal results contain center results for all corner nodes, when you request results only at the center location.
