ATA Engineering Announces the Release of IMAT v7.3.0

Enhancements include new visualization capabilities, faster processing of large numbers of results, and a new modal parameter estimation method

SAN DIEGO, Calif., April 17, 2019 – ATA is excited to announce the release of version 7.3.0 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 v7.3.0 to work with MATLAB R2019a as well as previous releases back to R2016b. IMAT v7.3.0 also supports Abaqus 2018.

Notable IMAT Upgrades:

IMAT’s readadf also now supports the new format of ADF function data files (AFU) introduced in Siemens NX 12.

Notable IMAT+FEA Upgrades:

IMAT+FEA’s vtkplot now offers a way to visualize mode shape results with arrows sized by magnitude, allowing you to more easily identify errors when comparing similar models and highlighting local area deformations that might otherwise go unnoticed.

Visualize deformation using arrows in VTKPLOT.

IMAT+FEA’s readnas function has been updated with several helpful new capabilities:

  • Importing large numbers of random and transient analysis results is now up to 100 times faster, significantly increasing your productivity.
  • Eliminate the need for custom processing or the tedium of hunting down and consolidating all your bulk data from partitioned bulk data files before importing—simply instruct IMAT to skip missing include files.
  • Acoustic analysis output from NX Nastran can now be imported, opening up IMAT’s capabilities to more data types.

Notable IMAT+Modal Upgrades:

IMAT+Modal’s AFPoly has been reincarnated as OPoly as a broader name encompassing expanded orthogonal polyreference capabilities. AFPoly previously offered the AFPoly method (a Laplace-domain orthogonal polynomial algorithm, now called LDOP) as its exclusive solver. OPoly has added a new, complementary solver called ZDOP (z-domain orthogonal polynomial algorithm), giving you another option for modal parameter estimation. More information on both methods is available in the OPoly user’s guide.

Download IMAT v7.3.0

IMAT v7.3.0 is available to any IMAT user who is current with maintenance, enhance­ments, and support (ME&S). There is no cost for upgrading to v7.3.0. Customers can download the latest version here. Please note that this version requires Sentinel RMS 9.2.0 or higher.
