COMPAS is an analysis tool used to optimize material characterization test programs and characterize novel and advanced engineering materials, ultimately reducing costs and schedule of bringing highly engineered products to market. COMPAS provides the means for determining the value of any given test within a full material characterization test matrix, accurately simulating linear and nonlinear material responses accounting for stochastic effects, predicting full property sets from limited data, and modeling multiscale thermomechanical behavior. COMPAS is deployed as an Abaqus plug-in, where Abaqus plug-ins execute Abaqus scripting interface and Abaqus graphical user interface (GUI) commands and provide a way to customize user interaction with Abaqus/CAE. COMPAS is modular in design and made up of different process flows, with each process flow having associated modules that guide the user through the specified analysis process. COMPAS started as a composite material tool but is now being extended to include additively manufactured materials. COMPAS has also be utilized as part of the multi-physics tools developed by ATA to simulate structural, thermal, fluid, and ablation in modeling of hypersonic vehicles.

IMAT is a suite of utilities offered by ATA that facilitates data sharing between MATLAB, test software, and analysis tools including Abaqus. The IMAT Toolbox provides a framework for easily importing FEA simulation data and measured test data into the MATLAB environment to access its versatile programming and mathematical strengths. Powerful and complex operations may be performed on the data while preserving all of its Abaqus data descriptive attributes so it can be imported back
