ESRD, Tech Soft America announce multi-component Licensing Agreement

(October 10, 2001)
Engineering Software Research and Development, Inc. (ESRD), a leader in FEA technology, and Tech Soft America (TSA), the leader in component graphics technology for the CAD/CAM/CAE industry, today announced a technology licensing agreement to incorporate TSAs HOOPS 3D Application Framework, Parasolid Geometric Modeler from UGS, and CAD data translators into the pending release of StressCheck, ESRDs industry standard aeronautical failure analysis software for composite bonded joints.

Kent Myers, Founder and Vice President of ESRD commented, "At ESRD we realize our resources are best applied to our areas of core competency - the robust solvers that make StressCheck such a valuable product to our customers. By leveraging multiple components from TSA we were able to rapidly design, develop and ship a complete and advanced solution, including sophisticated visualization, powerful modeling and CAD data translation while focusing on our true value-add. Were very pleased with the technology and support we received through TSA and the product we are able to produce through this technology licensing partnership."

Added Ron Fritz, Co-Founder of Tech Soft, "ESRD is a perfect example of how a focused team of experts in a specific engineering domain can partner with TSA as a virtual extension of their R&D team to deliver a powerful product - all with a minimum expenditure of development resources. ESRDs successful shipment of StressCheck demonstrates the value we provide in enabling a developer to produce advanced products with our bundled component solutions. Were delighted to be a part of their success."

StressCheck 6 sets a new standard for computer aided engineering by providing the most advanced FEA technology, with industry leading accuracy and reliability, delivered in an easy to use, parametric, and fail-safe environment. Furthermore, StressChecks unique infrastructure supports corporate requirements for standardization, provides a repository for corporate design knowledge, and is packaged for use by analysts and non-specialists, working as a team. Using its new Component Object Model (COM) interface, StressCheck can be integrated into a corporate engineering design environment to serve as an FEA-based replacement for outdated closed form solution methods. This release also introduces a new 3D automeshing capability, based on a 3rd party component from Simmetrix Inc., which ESRD expects will significantly broaden the market for use of the StressCheck product.

StressCheck models advanced composite material structures, homogenizes laminated ply layups in 2D and 3D as well as provides advanced post-processing capabilities to evaluate various failure criteria. Its unique p-version implementation of material and geometric nonlinear analysis may be used without model changes. The application also allows an engineer to analyze thermal problems including steady state heat transfer, radiation, and temperature dependent materials.

The HOOPS 3D Application Framework (HOOPS/3dAF) consists of a highly optimized integrated suite of industry leading software components. The HOOPS/3dAF provides a flexible architectural foundation, based upon a suite of modular application components, that enables the rapid development of design, visualization, and engineering applications for Windows, Unix, Linux and the Web. With the HOOPS/3DAF the base infrastructure for CAD/CAM/CAE applications has already been optimally designed and implemented and includes advanced features such as Large Model Visualization, Web Publishing and Streaming. Application developers can immediately begin implementing features using the APIs of the HOOPS/3dAF components, saving significant time and money while focusing more resources on their true value add.

Parasolid is an industry-leading component geometric modeling product with technology and innovations that power today's most advanced mechanical CAD/CAM/CAE applications. Parasolid's Extreme Modeling is a series of well-integrated, proprietary technologies that provide the ability to confidently model the most complex parts and assemblies found in any industry. In addition, Parasolid pioneered the first production implementation of a symmetric multi-processing (SMP) enabled geometric kernel that provides significantly increased performance on today's multi-processor computers. Furthermore, Parasolid delivers an interoperable Data Pipeline allowing Parasolid-based systems to share and exchange geometric data without translation using its de facto standard XT file format. More than 240 Parasolid-powered applications have shipped or been announced and more than 230 organizations have licensed Parasolid. In addition to its use in UGS' Unigraphics and Solid Edge products, licensees of Parasolid include Parametric Technology, SolidWorks (a subsidiary of Dassault Systèmes S.A.), Bentley Systems, CADKEY, ANSYS, Mechanical Dynamics and MSC.Software. Over 720,000 end user seats have the Parasolid kernel embedded within them. For more information please visit on the World Wide Web.
