So basically my entire modal is huge and many different parts. So to avoid long computational time, I am using block of same weight as of original engine. An engine is mounted on feet and then feet on pedestal. So what's best way to connect engine on feet and feet on pedestal to get correct natural frequencies?
Also I am not considering Pre-Stress Analysis because for modal analysis unbalance forces don't need be consider, correct?
Thank you in advance for all your help and guidance Sir. I really appreciate it.
