5.3 Measurement execution: impact locations card

The impact locations card shows the impacts as defined in the Prepare Module. When selecting an excitation point, the camera moves automatically to that point. In some cases (e.g. parts that block the view) this may be undesired; the camera can be locked by right-clicking in the 3D viewer and activating “Lock view port”.

The measurement execution can be fully controlled from a normal keyboard; see the table in 2.3 Keyboard commands for the key commands.

Impact ordering and grouping

By default, the order of the excitations within the Impact Locations card are grouped by VP.  By clicking on the Ungroup button, the excitations are instead sorted by index number.  They can be again re-sorted by clicking on Group by VP.

A similar option is available for grouping of multiple input sources, if multiple are defined. The grouping button will show up and can be used to group the measurements.

Incorrect excitation location

If impact data is accidentally saved in the wrong excitation point, these can be moved over to the right excitation point using drag and drop. A context-menu action is also available. Note that if data already exists within the new excitation entry, the measurement name will be updated with the appended name of those data.

Star impacts

A star is shown next to each measurement, which can be toggled on/off by pressing S. This has no effect for any computation, but helps memorizing this measurement as the one hit that was “spot on”, which you might want to use as a reference when seeking for alike measurements.

Delete (rejected) measurements

To preserve file size and general performance of DIRAC, it may be desired to delete all invalidated measurements after completion. To do so, right-click on the relevant category and click on the relevant option.
