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 standard keyboard; see the table in 2.3 Keyboard commands for the key commands.
With the automatic measurement selection (AMS) DIRAC can automatically select the most similar measurements. Similarity is based on the coherence of every possible pair of measurements. This function can be activated after the measurement or used in live mode during testing.
Double pulses and other faulty measurements are automatically excluded from the results.
If the measurements do not fulfill the AMS settings, only the first measurement is selected.
After a measurement, you can apply AMS to a single excitation point or to all of them.
To apply AMS to a single excitation, complete the next steps:
To apply AMS to excitations in the project, complete the next steps:
When in live mode, the most similar measurements will be selected every time a new measurement is recorded.
To activate AMS in live mode:
You can create multiple AMS presets with different settings.
To create and edit a preset for the AMS, complete the next steps:
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.
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.
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 to memorize this measurement as the one-hit that was “spot on”, which you might want to use as a reference when seeking for similar 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.
