ADINA理论与模型3

Chapter 1 Introduction

In this Theory and Modeling Guide, the theoretical bases and guidelines for the use of the ADINA CFD and FSI capabilities are presented. These capabilities are implemented in ADINA-F program code. Hence, we use the term ADINA-F throughout this Guide to refer to CFD and FSI capabilities.

The intent with this Theory and Modeling Guide is

• To provide a document that summarizes the methods and assumptions used in the computer program ADINA-F.

• To provide specific references that describe the features of ADINA-F in more detail.

Hence, this manual has been compiled to provide a bridge between the actual practical use of the ADINA-F program and the theory documented in various publications. Much reference is made to the book Finite Element Procedures (ref. KJB) and to other publications but we endeavored to be specific when referencing these publications so as to help you to find the relevant information.

ADINA-F is a general finite-element/finite-volume code that can be used for analyzing fluid-flow related problems. They can be incompressible, slightly compressible, compressible flows and flows in porous media. Most importantly, solid models created in ADINA can be coupled with any fluid model for analyzing fluid-structure interaction problems.

This manual is organized as follows.

We briefly describe the capabilities of ADINA-F and the structure of this manual in the current chapter.
