Describing active solid conductors (3D)

Classification

In a general approach it is possible to differentiate two types of active solid conductors:

• “open” (ex.: U shaped, or E shaped…)
• “closed” (ex.: toroidal shaped, or…)

These conductors are briefly described hereafter and in more detail in the following paragraphs.

“Open” solid conductor

An “ open ” solid conductor is a conductor with any shape (See example on the opposite figure)

Important: The supplied electric terminals of the solid conductor must be on the edge of the domain (symmetry or periodicity plane).

«Closed» solid conductor

A “ closed ” solid conductor doesn't exist in the real life. A cut is necessary to carry out the connection with the electrical circuit (see figure below).

In Flux 3D, we can model a “closed” solid conductor, superimposing the two electric terminals without a short-circuit.

A “ closed ” solid conductor has its electrical terminals “superimposed” from a geometric point of view. The same geometrical face corresponds to the two terminals of the solid conductor.

Orientation of the current

The orientation of the current is set by:

• the entering and exiting faces of the current, for open conductors

• an orientation line

  for closed conductors
