General approach: tube conductor and assimilation conductor

Introduction

This paragraph deals with:

  • the general modeling process
  • the two modes of description of the conductors in Flux PEEC

    (called tube conductor and assimilation conductor )

General process

The general process of modeling in Flux PEEC is presented in the table below. The elements necessary for the description of a conductor and the concepts of tube conductor and assimilation conductor are presented in the following blocks.

Stage Description
1 Choice of an application (scenario definition)
2 Conductors description: tube conductor / assimilation conductor
3 Addition (possibly) of a ground plane
4 Electric description *
5 Meshing
6 Solving process (according to the scenario)
7 Results post-processing

* Electric description depends on the choice of the application (Supplied conductors / Conductors impedance)

Description of a conductor …

The description of a conductor includes:

  • its geometrical description (topology of the conductor)
  • its physical description:
    • information related to the material (resistivity and possibly relative permeability)
    • information related to the meshing (type of mesh, density)
  • the description of its terminals (for electric connections between conductors)

Two modes …

Two types of conductor description are proposed in Flux PEEC, called tube conductor and assimilation conductor. These two modes of description are presented in the two tables below.

The tube conductor mode enables the description of following conductors Principal characteristics
  • unidirectional
  • simplified geometrical description (geometric tube)
  • automatic physical description (material of the application / mesh according to the reference frequency / input-output terminals)
- of rectangular cross-section
- of variously-shaped full cross-section
- of variously-shaped hollow cross-section with constant layer thickness
The assimilation conductor mode enables the description of following conductors Principal characteristics
  • unidirectional
  • detailed geometrical description (points, lines, faces, volumes)
  • detailed physical description (material, mesh, terminals)
- of variously-shaped cross-section  
- of full cross-section (rectangular included)
- of cross-section characterized by an unspecified number and various shape of holes
  • bidirectional

These two modes of description are detailed in the following paragraphs.
