Release notes

SOURCE version 2.0

May 2022

This release of SOURCE is soon to be expected! SOURCE v1.6 served as a prequel or Beta to SOURCE v2.0. See below for all the new and improved features. All feedback received on these features in v1.6 will be reflected in SOURCE v2.0.

 

SOURCE version 1.6

11 April 2022

This release of SOURCE is the last release in the 1.x series. It serves as a prequel or Beta to SOURCE v2.0 coming in May 2022. All feedback received on the features mentioned below will contribute to a further improved SOURCE v2.0.

Renewed 2D Graphing environment
The graphing experience in Analyze has been completely renewed. You now have the ability to manipulate pages, the layout of various axes in a customizable grid, and the information you wish to view. This comes with the ability to save pages and layouts in the SOURCE project file, such that these are restored when reloading a project. Some features in short:

  • SOURCE is capable of re-calculating analyses on demand, namely by asking for a refresh of loaded graph axes.
  • One can create a simple uniform grid layout by simple drag-drop of source and analyzed datasets using the added visual cues, or by dragging the existing graph panels around with the mouse.
  • Alternatively, one may adjust the grid rows and columns using a “layout mode”, such as changing the relative sizes or adding rows and columns for use in a later stage.

While this mechanism is all-new, you may need some practice to explore the capabilities. An instructional video will be put on the VIBES Academy.

3D Viewer for Operational Deflection Shape animation
An additional 3D Viewer card was added to the Operational Data module. This requires the “src-ods” license.

The 3D Viewer allows displaying Operational Deflection Shapes (ODS) of operational datasets. It shows nodes and line elements and can display geometries when loaded from a DIRAC file.

  • In order to get started, one first loads a DIRAC project to select and import the contained geometries, but also to create master channels containing accurate position and direction information.
  • Operational data needs to be mapped to these master channels in order to be used for ODS animation.
  • Dragging an operational dataset into the 3D Viewer will result in displaying the content. Nodes are shown for the active collection of channels, while line elements can be added by the user for clear visualization.

Controls for selection and navigation will be further improved towards SOURCE 2.0.

VP Transformation on direct blocked force measurements
This feature uses the new possibilities for managing Virtual Points, VP channels, and the option to mark imported channels as VP channels. The Direct Blocked Force analysis will now calculate a VP transformation on measured force channels if they are grouped to VPs and the associated VP channels are used in the analysis. For assistance in getting started with this feature, please reach out to support@vibestechnology.com.

Strip plots for order cuts
In addition to showing order cuts over time, RPM and frequency, one now also has the possibility of creating strip plots that show all channels along the vertical axis.

Other changes:

  • Project loading progress: when loading a SOURCE project, you will now be able to monitor the progress in a window and cancel when needed.
  • Improved Token control in the plot and axes legends: the control that shows tokens when hitting “{“ now shows previews of the token values and has an improved experience. You can now also set a default legend template in Preferences.
  • Edit list entry names on double-click F2: When working with datasets, the name is not automatically editable anymore. To edit, double-click with the mouse, press F2 or hit Enter.
  • General performance and stability fixes.

 

SOURCE version 1.5.2

15 February 2022

Changes:

  • The speed of MAT-file imports has been significantly improved.
  • Improvements to time-domain signal processing to ensure proper lengths of time blocks.
  • A preference was added to control how the naming and grouping of operational datasets is established upon import.
  • Some bugs have been fixed related to unexpected shutdowns.

 

SOURCE version 1.5.1

4 February 2022

SOURCE version 1.5 brings new functionalities for order analysis, operational consistency, and several improvements to graphing.

Support for order cuts
Next to order spectra, SOURCE now supports single order cuts as well. Typically, single order cuts are created by processing a time measurement with a specified RPM channel, e.g. in Müller-BBM PAK or Siemens TestLab. SOURCE imports these order cuts from ATFX files. All cuts belonging to the same measurement are grouped into an “Order Cuts” dataset.

  • Order cut magnitudes can be plotted over time, RPM, and derived frequency. The derived frequency is computed as $$ f(t) = \mathrm{ord} * \mathrm{rpm} (t) / 60 $$. These x-axes are selected by right-clicking on the X-axis. A-weighting can be applied as well, in which case the derived frequencies are used to get the right scaling per point regardless of the current X-axis.
  • Order cuts can be used in analyses, just like any other operational dataset. This leads to the computation of order-based Blocked Forces and component TPA.
  • Order cuts can be exported to ATFX only.

Operational Consistency
A new unique feature introduced in SOURCE v1.5 is “Operational Consistency”. Operational Consistency can reveal incorrect behavior in the operational measurements, i.e. if there are overloads or strange physical (non-linear) phenomena. It furthermore indicates whether the sensors are consistent with one another: no sensors have been moved or gotten loose. It does so by evaluating the consistency through Virtual Point Transformation of the response data. This needs geometrical data, i.e. the location and direction of the response channels, to be set correctly.

The most convenient way to use Operational Consistency in SOURCE:

  1. Load in a DIRAC project and use the channels as master channels. This contains accurate geometrical information already. Also, Virtual Point groupings are automatically assigned to the master channels.
  2. Map the channels of the operational datasets to the master channels as usual.
  3. Right-click on the operational dataset and choose Plot > Operational Consistency. This will only be available when mapped channels are found that have a virtual point grouping.

 

Improved data import & automatic channel mapping

  • An import dialog is now shown for DIRAC project imports. This allows to select the desired datasets from all matrix presets as defined in DIRAC. Also, one can define and review channel type mappings that are made based on the Description field of the sensors and excitations. This way, the right master channels can be generated and configured automatically.
  • When importing other data formats, the user will be prompted whether or not the channels need to be “auto-mapped”. If yes, channel mappings are made based on the name of the channels.
  • When importing ATFX files, SOURCE will now try to rebuild the project hierarchy to match the way the data was organized in the original application. This feature is enabled by default but can be disabled in Preferences under the category Data Import.

UFF export of operational data
UFF export is now available for any time or spectral dataset. All selected datasets are written into one *.UFF file.

Graphing improvements
The graphing functionality of SOURCE 1.5 has been substantially improved.

  • There is a new “sum level plot”, which shows sum levels over time. This operates on both time and spectral data. The sum levels are calculated according to the spectral settings in the top left of the axes.
  • The selection of channels and blocks/columns has been improved, along with the interaction for pinning channels.
  • Added plots to existing axes will automatically be assigned a new color.
  • Curve legends could already be defined dynamically using so-called “tags”, by typing for instance {Dataset.Name} or {Channel.Quantity}. The available tags are now previewed when typing “{” in the text box for legends. This feature will be further improved in the next release.

Other changes:

  • Fourier transform (FFT) is now adjusted to separate the DC (0 Hz) component from a signal before any windowing is applied. This DC component is then added to the spectrum separately. This way, the DC value does not get distorted by applying a spectral window.
  • In calculations of matrix-inverse and matrix multiplication where the frequency vector of the two datasets does not match, linear interpolation is now being applied. This enhances the quality of source characterizations.
  • In time-domain conversion, you now have the option to apply low-pass and high-pass filtering on the spectra. This gets applied before they get converted to the time domain.

 

SOURCE version 1.4.1

17 October 2021

Changes:

  • When loading a project, SOURCE checks for differences between the source data files and those defined in the project. If any files have been changed, a window is shown where one can select the new dataset and verify its size.
  • The speed of calculation and use of memory has been improved.
  • A bug was fixed where the FRF Data graphs card did not show phase and coherence anymore.

 

SOURCE version 1.4

4 October 2021

SOURCE version 1.4 adds the possibility to perform order-based Blocked Force and TPA analyses from pre-computed Order spectra.

Handling of Order Spectra in TPA analyses
SOURCE now accepts order spectra from ATFX files and allows to use these in any analysis. Such Order Blocks datasets are complex-valued spectra expressed against an order axis rather than a frequency axis. In conjunction with the RPM channel, the order axis gives access to the instantaneous frequencies for a given speed. When used in an analysis with an FRF matrix, SOURCE interpolates the FRF matrices to match the order frequencies of the operational dataset. This way, you can easily create order blocked forces as well as order TPA syntheses, which can be plotted in Analyze or exported to ATFX for further analysis.

Upgrades to the VIBES License Manager
Several issues have been addressed to improve the useability and stability.

  • The connection to a Cloud Licensing Server (CLS) will now work correctly on the first start when working behind a proxy server.
  • An issue was resolved where borrowed licenses may disappear for a certain amount of days.
  • When using different CLS servers for different products, the License Manager now correctly shows the one you are currently connected to. It also prohibits returning licenses to the wrong CLS server.
  • More user feedback has been added to inform on any connection errors.
  • A yellow or red color now highlights soon-to-expire licenses.

SOURCE manual to online VIBES Academy page
The manual is now replaced by a link to the new online VIBES Academy page.

Other changes

  • Segments and sequences have better automatic naming and are placed directly under their associated dataset(s).
  • ATFX import: channels expressed in non-SI units, e.g. km/h, are now scaled accordingly.
  • Audio playback: it is now possible to select the channel to playback in the toolbar.
  • The Auralization license (src-aur) is now needed to compute time domain conversions and export to WAV.
  • Many minor bug fixes and UI improvements.
