Free Free Modal Analysis using Hypermesh - Optistruct Solver | Modal Analysis Deck Preparation
Modal analysis is the first step during the dynamic simulation of any component using CAE.
This tutorial explains the process to set up and run a modal analysis subcase using the Optistruct solver in Hypermesh.
The main objective of modal analysis is to calculate the natural frequencies of vibration of any given component.
This is usually done using the Real Eigenvalue Extraction method using the EIGRL card.
In this simulation, we will find the first 15 modes of vibration of BIW
