drucker-prager, then frequency extraction?

[mmmbordo643]

xerf,

Thank you for all your help. One final question for you if you don't mind, or anyone else. After I run a compaction simulation, is there any way to take the compact and run a frequency extraction so as to compare natural frequencies to the pre-compact?

thanks again,
Chris

You can try to define a "Frequency" step in the end of the analysis.

Procedure type: Linear Perturbation
