ATA Engineering Announces the Release of IMAT v7.5.0

Enhancements include a new substructuring capability, accelerated import of OP4 files, and improved memory efficiency when reading OP2 data

SAN DIEGO, Calif., April 8, 2020 – ATA is excited to announce the release of version 7.5.0 of the IMAT family of software products. IMAT is a MATLAB toolbox designed for test and analysis engineers who process data from a variety of sources. This release brings a number of useful new enhancements to the powerful functionality available in IMAT.

ATA is committed to providing new IMAT releases in conjunction with new MATLAB releases. ATA Engineering designed IMAT v7.5.0 to work with MATLAB R2020a as well as previous releases back to R2018b. IMAT v7.5.0 also supports Abaqus 2019 and Femap 2020.1.

Notable IMAT Upgrades:

Put all the pieces together

In this release, IMAT has added a powerful substructuring capability that allows you to build and analyze systems of test and/or analytical components: now you can assemble models from the component representations you have available so you can analyze the system as a whole. This capability implements methods used in the Transmission Simulator work by Sandia National Labs and the University of Wisconsin, which let you fine-tune hard and soft component connections to achieve more-accurate results.

New substructuring capability in IMAT

Substructuring lets you add or subtract components to form a system FEM.

Notable IMAT+FEA Upgrades:

Increase productivity when processing Output4 data

Save time and increase throughput when you need to read OP4 data. IMAT+FEA’s readnas has been enhanced to process OP4 file data faster—in the case of some larger files, processing time may be reduced from hours to just minutes.

Access more Output2 data with improved memory efficiency

Need to process large amounts of OP2 data but previously ran out of memory? Significantly increased memory efficiency in IMAT+FEA’s readnas now allows you to read the data you need using the “asraw” option, even from very large files.

Download IMAT v7.5.0

IMAT v7.5.0 is available to any IMAT user who is current with maintenance, enhance­ments, and support (ME&S). There is no cost for upgrading to v7.5.0. Customers can download the latest version here. Please note that this version, like other recent versions, requires Sentinel RMS 9.2.0 or higher.
