# Plotting a 2D evolution curve

## Definition

A 2D evolution curve represents the values taken by a global (scalar) physical quantity according to the frequency.

## Physical quantities

The physical quantities that can be displayed with 2D evolution curves are:

• current through a terminal
• current in a unidirectional conductor
• current in an electric component
• Joule losses in a unidirectional or bidirectional conductor
• Laplace force (average component as well as pulsating component) o n a unidirectional or bidirectional conductor

For all quantities related to the current, the curves representing the magnitude, the phase, the real part and the imaginary part are created and displayed.

For the average component of the Laplace force, the curves representing the three components (X, Y and Z) are created and displayed.

For the pulsating component of the Laplace force, the curves representing the magnitude, the phase, the real part and the imaginary part of each of the three components (X, Y and Z) are created and displayed; representing altogether twelve curves.

## Creating and displaying 2D evolution curves

To create and display 2D evolution curves, the user has to:

Step Action Result
1

Open the 2D evolution curve dialog box:

• either by clicking one of the following icons:

• or from the menu bar by clicking Post processing followed by 2D curve (evolution) and then select:

Current in a terminal or Current in a unidirectional conductor or Current in a component or Conductors losses or Conductors Laplace force

2a

In the dialog box that appears:

• define the name of the 2D evolution curve; a default name is proposed by Flux PEEC
2b
• only in the case of Current in a component, select the kind of component: Resistors, Inductors, Capacitors, Voltage sources or Current sources
2c
• select the entities (terminals or conductors or components) on which to plot the values taken by the physical quantity
2d
• only in the case of Conductors Laplace force, choose either the average component or the pulsating component
2e
• click on OK
The 2D curves are displayed in a new specific sheet with the name of the physical quantity considered.
