ATA Engineering Announces the Release of Vibrata v5.0.0

SAN DIEGO, Calif., February 9, 2023 – ATA is pleased to announce the release of version 5.0.0 of Vibrata. Vibrata is an advanced dynamic analysis software package designed to give Femap® users powerful response analysis capabilities. Vibrata allows users to easily define, solve, and display results for the most challenging dynamic simulations, and offers an easy-to-use interface and unlimited customization capabilities through its integrated MATLAB® interface. This release brings a number of useful enhancements to Vibrata, including an overhaul of the event file format for easier use. The new format clarifies how the various damping quantities are applied and removes ambiguity regarding the individual contributions to the total damping. In addition, the main Vibrata GUI has been updated to display the event file location, and the results display now more accurately shows where results are stored. The transient solver has also been enhanced for improved performance to solve some classes of problems more quickly.

New Vibrata Features:

Updated Graphical Interface

Vibrata’s main interface has been updated to show the event file location on the file system in the Events section. This makes it easier to manage your Vibrata files and keep track of where the events are located.

The location of contour output results has also been enhanced to specify that they are stored in Femap, in contrast to XY results, which are stored in a .vra_xyout file. Related to this change, Vibrata no longer creates an Analysis Set in Femap for contour results, making it easier to use the same MODFEM for different events.

Vibrata GUI
The main GUI has been enhanced to make it easier to see where your data is located.


Overhauled Event File Format

The event file format has been revamped to be easier to read and edit. In particular, the damping definition is now separated into independent schedule, mode-specific, and matrix definitions, clarifying the source of the individual damping contributions to the total damping. Old event file formats are still supported and are automatically converted to the new format when loaded. Finally, damping matrices contained within the OP2 file are now automatically applied during event creation, saving you a step and reducing the potential for errors.

We encourage customers to continue to send enhancement requests, as these help to make our product better.
