Results Visualisation

open the results visualisation window

The results visualisation window is not the same for the far field and the near field. However, the common points are the following :

If a frequency range was computed, a frequency must be selected.

It is possible to modify the geometry selection or the contributions. Only the selected parts of the geometry and the selected contributions will be used to generate the displayed result. If nothing is modified, the selection is supposed to be the same than for the computation (default). If the selection includes parts or contributions that weren't selected for the computation, these parts or contributions will be ignored. This functionality provides a good physical insight into scattering process.

Once a results visualisation is generated with the button show, GID is in post-processing mode. The GID function toggle pre/postprocess must be used to come back to the pre-processing mode. This must be done to modify the computation or the visualisation parameters.

Far Field :

The far field component must be selected (Etotal, ETheta, EPhi or Polarisation).

The result is represented in dB scale. It is possible to modify the minimum level, which corresponds to the level at the center of the spherical coordinates.

If Polarisation is selected, 2 additional lines are plotted for each direction of observation. They represent the major and minor axes of the elliptic polarisation.

The whole radiation pattern can be displayed in 3D. It is also possible to draw only a radiation pattern for a given phi angle with the check button Phi Plane.

Near Field :

There is nothing to do for the near field results visualisation.
