All-new release of DIRAC V3!

DIRAC version 3.0 presents a major release of DIRAC. The most substantial changes are found in the Analyze module, which has been redesigned entirely to be optimized for large measurement campaigns and hundreds of channels. DIRAC also offers a brand new Photo Viewer feature in Prepare to document your measurement set-up. Other modules have undergone smaller changes. Find here a summary of the newly added and changed features.

• Faster startup and general performance. DIRAC V3 has undergone performance improvements on every aspect of the application. This improves speed as well as stability and makes working with large measurement campaigns more enjoyable then ever before.
• New Getting Started video added to the home screen. This video contains valuable information for any first-time user of DIRAC.
• Upgraded User Manual with tips on how to make efficient use of the new features in Analyze.
• Upgraded License Manager. For users of a Network License Server, authenticated login is added.

• New Photo Viewer feature. Import the photos that you took during the measurement preparation and execution, or any other picture you like to carry with your DIRAC project. The photos can be tagged to categorize and filter them easily. The Photos can be matched to a viewpoint in the 3D viewer, so you can compare the reality with the digital set-up.
• Shortkeys for Move (Y) and Move on geometry (M), that act directl on the selected object.
• Virtual Points can be assigned a node number. This node number field is exported to MAT-files.
• The visual size of the excitation arrows can be adjusted under Settings > 3D Viewer.

• DAQ Wizard: Connect Hardware. Issues previously reported where the MK2 system reboots unexpectedly have been resolved.
• PAK Live versions 3.2.x and 3.3.x have been tested and implemented. To get the best experience when working with your MK2 devices, it is recommended to update PAK Live to the latest available version. To do so, please use PAK tunes or consult MBBM support.
• Improvements on PTP synchronization when using multiple MK2 devices. The PTP synchronization is now picked up correctly when adding new devices through the Device Cloud I/O Service.

• Improved support for ASAM-ODS ATFX import. The speed of reading has been improved. Typical data structures as exported by MüllerBBM-VAS PAK, Siemens Test.Lab and HEAD Acoustics are generally supported.
• Added support for MATLAB MAT import. Supported data structures are DIRAC exports and VIBES Toolbox for MATLAB exports, when saved using the ‘native’ option.

• Redesigned matrix viewer. FRF matrices can now be shown for the four Measured and/or Virtual Point quadrants, or subsets of these. More can be read in the DIRAC User Manual.
• Custom matrix presets to down-select parts of the FRF matrix for more focused analysis based on custom selection of channels. These custom-defined matrices can be used for data export to ATFX and MAT as well.
• Channel quick filters to only show some sensor groups for quick analysis.
• ODS animation now allows to animate the virtual points along with the sensors.
• Renewed quality criteria. The FRF coherences and virtual point consistencies now also get propagated into the virtual point transformed submatrices. This means that one can assess the coherence and the consistency of a virtual point FRF. Reciprocity has become a separate mode and only shows quality data for the two-sided virtual point FRFs, for which reciprocity can be evaluated.
• The new validate card now has separate tab pages showing quality and control over the measurements, response consistency and force consistency.
• New feature to (un-)include channels in the virtual point transformation. The participation of individual sensor and excitation channels in their associated virtual points can be toggled on/off in the response consistency and force consistency card. The VP transformation is recalculated in real-time. This makes it easier to detect “bad” impacts or sensor channels and either optimize their location/direction or leave them out of the calculations.

• Improved ATFX export. It is now possible to export any FRF matrix subset or custom preset as defined in Analyze. All datasets get written into a single ATFX header file. Measurement locations and directions are exported correctly as well.
