Arrows: about
Plotting of arrows
Spatial vectorial quantities can be displayed by means of colored arrows on the different supports.
Support
The support for the plotting of arrows are:
- unidirectional conductors
- bidirectional conductors
- 2D grids
Spatial quantities
The spatial quantities that can be displayed by means of arrows are:
- the current density and its three components (X, Y or Z)
- the magnetic flux density and its three components (X, Y or Z)
- the Laplace force density (the average component as well as the 2ω pulsating component) and its three components (X, Y or Z)
Meaning of the arrows
The spatial quantities considered are displayed by means of arrows according to the following rules:
- the color of the arrows is proportional to the modulus of the quantity
- the orientation of the arrows points the direction of this quantity*
Note: * Obviously, if the quantity selected is a component of a quantity, the
orientation of the arrows will be the direction of that component.
Computation points
The points where the arrows are computed depends on the spatial quantity selected but are in general highly linked to:
- for unidirectional conductors, to the mesh and the additional points due to the discretization in the length for the post-processing*
- for bidirectional conductors, to the mesh
- for 2D grids, to their own discretization as described in § 2D grids: about
Note: * To discretize in the length a unidirectional conductor, the user must first create
it and then edit its features from the Data tree. In the Mesh tab
of the window which appears, the user can define the number of discretization points
along the length, as shown in the figure below.
