Chapter 1 Introduction

 

ADINA-EM is a general finite-element/finite-volume code that can be used for analyzing electromagnetic (EM) problems. The solutions can be coupled with CFD solutions in the ADINA-CFD+EM package that includes both ADINA-EM and ADINA-CFD.

 

In this Theory and Modeling Guide, the theoretical bases and guidelines for the use of the ADINA-EM capabilities and the CFD-EM coupled solution procedure are presented.

 

This guide is organized as follows. A brief introduction is given in Chapter

1. It includes all key ingredients in ADINA-EM and the CFD-EM coupling. For experienced ADINA users, it is enough for them to start.More details on some important subjects are given in the remaining chapters.

 

The governing equations of first and second orders, in both E-H and A-φ mathematical formulations are presented in Chapter 2. The modules and analysis types are also introduced in ADINA-EM.

 

The concept of path is described in Chapter 3. The path is used to ease the input of space-varying directions and functions.

 

In Chapter 4, all the parameters required in element groups are described, including material data, electromagnetic sources and the control parameters.

 

Various boundary conditions available in ADINA-EM are detailed in Chapter 5, including their mathematical representation and the required input parameters.

 

The discretized linear equations are solved using iterative solvers. In Chapter 6, we introduce the control parameters and explain how they work during the iteration procedure.
