Mode Superposition Transient Analysis Using Ansys Mechanical - Lesson 1

Transient Analysis is used to study the change in a system's behaviour over a specific time period, by considering the temporal effects of inertia and damping. For example, when a car drives over a bump, its suspension system deforms temporarily to ensure a smooth ride. Transient Analysis can be solved using two methods, the Full Solution Method and the Mode Superposition Method. In this video, we will focus on the Mode Superposition Method, which is a linear method and is highly applicable to most engineering vibration simulations with the benefit that it is much more computationally efficient compared to the Full Solution Method. In this video lesson, we start with a short lecture and then get into a workshop example in Ansys Mechanical.

Amazing Video. Very helpful! Thank you guys so much 😁

[@omarsaif523]

I tried the solve function and it says 'general error' thus can't solve the problem. Please provide a response.
