Non-connected volume regions of type "coil conductor region" in
Flux 3D
Overview
Until version 2022.1 of Flux 3DTM , volume regions of type "coil conductor
region" had to be assigned to a single connected group of volumes of the geometry. A
possible geometry for such regions is shown in Figure 1where nine
connected coil conductor regions were necessary to describe the windings of a motor.
There are three coil conductor FE coupling components in the project. Each coil
conductor had to be assigned to three regions.
This constraint has been lifted in Flux 3DTM 2022.2: in this new version,
regions of type "coil conductor region" may now be assigned to several non-connected
groups of connected volumes. The number of such volume regions in a project can
therefore be much smaller. A possible geometry for such regions is shown in Figure 2. Remark that
now, only three coil conductor regions are necessary to describe the windings of the
motor. Each of the three coil conductors is assigned to a region.
Note: This new possibility of having non-connected
volume regions of type "coil conductor region" in 3D is available only for
Coil conductor region without losses or for Coil conductor region
with losses and simplified geometrical description. This feature is not
yet available for Coil conductor region with losses and detailed geometrical
description.
The new possibility is not available with the
“Analytical method or by interpolation from lines“, only with
“Method with electric conduction resolution + uniform J norm” to
compute the current density J in these regions (available from the
Solving menu, with the following choices: Solving process
options > Edit > Advanced tab). For the moment, a
Coil conductor region with losses and detailed geometrical
description, always uses the Analytical method or by
interpolation from lines.
Orienting coil conductor regions
The following two commands:
Orient wires of coil conductor region (completion mode), and
Orient wires of coil conductor region (modify mode).
are still required to assign the electric terminals to a coil conductor volume
region in 3D. In case of a non-connected volume region of type "coil conductor
region" with Internal terminals, Flux will ask the user to select the faces
on the input terminal and only one line defining the sense of the current for all
the groups of volumes. The faces on the input terminal must almost be in the same
plane and must be close to each other. An example is given in Figure 3 below.
