ATA Engineering Announces the Release of Vibrata v3.0.0

SAN DIEGO, Calif., October 3, 2019 – ATA is pleased to announce the release of version 3.0.0 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. The release brings a number of useful enhancements to Vibrata, including new capabilities that greatly improve solver performance and give you more insight into individual mode responses.

New Vibrata Features:

One of the most exciting new features in this version update is the incorporation of a Vibrata-specific database format (.vra5 file extension) that makes it possible to completely bypass Femap when importing OP2 files, resulting in significantly accelerated processing. Real-world testing with large models has shown speed improvements of 2 to 5 times—and sometimes much more. With this capability, Vibrata translates your OP2 file into the new database format and immediately starts running solutions.

Additionally, this version of Vibrata has added XY output to the Response Spectrum solver, making it possible to look at the responses of each mode before they are combined, giving you more insight into each mode’s contributions to the response and providing a convenient intermediate step for any necessary diagnostics.

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