This course aims to provide you with the framework to effectively performing fluid-structure interaction simulations using the ALE method in LS-DYNA. It is intended for analysts with good solid and fluid mechanics and thermodynamics background. In this class, the fundamental concepts of the ALE method will be discussed. Then a systematic modeling procedure will be presented which will help the students learn the required keywords and parameters and be able to construct actual models that simulate real physics. The course is meant to be comprehensive covering both concepts and applications. We hope that this class will provide enough information for you to build your own models accurately in a time-efficient manner. Please note that there will be extra examples provided that will not be covered simply due to time constraint, but hopefully they can serve as good reference for the students.
- Basic knowledge of solid and fluid mechanics & thermodynamics.
- Basic knowledge of LS-DYNA model construction & execution (Intro-Class equivalence).
- A good basic understanding of numerical/discretization methods.
The general concepts will be discussed by the instructor. For the practical examples portion, it will be a mixed approach. Some of the time the attendees will be constructing pseudo models. During this portion, for each example model, we will first define the physics of the problem. Then, the students will construct a pseudo-input file for the model (pencil-paper). Afterward, we will go over the modeling details together. For some of the examples, the instructors will define the problems and go over how to set them up.
