Within the quality card, information is shown about the VP conditioning and contributions. These can be used in the preparation phase of a project to design a measurement setup that provides a sufficient base for the VP calculations to come.
The Quality widget with Virtual Point Conditioning and Contributions
In the following video, the quality indicators of the Prepare module of DIRAC are explained.
Two conditioning matrices are shown on the left side of the quality card and shows how well the DoFs of each VP are conditioned, for respectively the VP response channels (left) and VP force channels (right). It is used as follows:
Two contribution matrices are shown on the right side of the quality card and show what the contribution is of every measurement DoF. Here, the response (sensor) channels are shown on top and the force (excitation) channels below. The contribution matrices apply to the currently selected VP, as chosen in the drop-down box in the top right corner. It is used as follows:
If one channel/excitation is dominating the contribution, that box will turn reddish, and additional sensors/impacts should be defined to capture that VP DoF.
