Post-processing of global quantities

Definition: reminder

The global quantities result from the integration of local quantities over the entire or only a part of the computation domain.

It can be a question of the:

  • magnetic force Fm, the magnetic torque Γm, the magnetic energy Wm,… in case of a magnetic application
  • electrostatic force Fe, electrostatic torque Γe, electrostatic energy We,… in case of an electric application
  • of the heat flux,… in case of a thermal application

Uses of global quantities

The global quantities can:

  • be directly computed ( preset computations )
  • defined/computed by interactive integration ( computation of integrals )
  • be stored in the Flux project and exported.

Different computations

The computation possibilities offered to the user are as follows:

  • Computation of preset quantities (specific to the physical application) *
  • Interactive integration of a spatial quantity on a spatial support (see table below)
Support Type of integral
volume surface line
Volume / Volume region / 3D Grid Volume Contour -

Face / Face region

/ 2D Grid

 - Surface Contour
Line / Line region / … - - Line
Note: * A detailed list of the preset global quantities available for each physical application is presented in volume 3 of this guide (§ related to the current physical application).
Attention: In the presence of symmetries/periodicities, the different computations are performed for the part of the device represented in the computation domain.

Results storage and exportation

The global quantities can be stored in the Flux project and exported. The different options are presented in the table below.
