Hello,

I am new to pipe stress analysis and have been thrown in at the deep end. The final part of the pipe stress analysis philosophy I need to assess is the modal analysis and ensuring the natural frequencies are not below 3Hz.

I know there is a way to do this in Caesar 2, however my questions is, is this an acceptable way of assessing the natural frequency in industry or is it best practice to use other software such as Ansys mechanical for such a task?

P.s. please don't be concerned, my work is being checked by a pipe stress engineer however I am having to pick up some of the work due to resourcing issues.
