CADSI Announces New Product Releases for Motion and Structure Analysis Embedded in CATIA.

CORALVILLE, Iowa--(BUSINESS WIRE)--July 18, 1997--CADSI (Computer Aided Design Software, Inc.) announces the release of CATDADS 8.5 and PolyFEM 3.0 for design simulation embedded in CATIA. With these enhanced versions, CADSI provides mechanical design engineers with powerful and unparalleled tools for motion and structural analysis in the CATIA environment. CATDADS 8.5 and PolyFEM 3.0 enable design engineers to simulate the full range of their product's performance during the design phase. CADSI is the only company that provides both structure and motion analysis embedded in CATIA for Simulation Driven Design.

"The new features of CATDADS 8.5 and PolyFEM 3.0 makes it easier for CATIA users to identify critical design parameters early in the development cycle. Recent multiple seat installations of our embedded CATIA software indicates a major market acceptance of our Simulation Driven Design strategy," states David Bird, vice president of marketing at CADSI.

CADSI is a Dassault Systemes Strategic Partner in the CATIA Application Architecture (CAA) program which guarantees continued joint development to improve ease-of-use and increase the power of future product releases.

CATDADS 8.5 - Dynamic motion analysis in CATIA enhanced features:

-- Dynamic motion simulation models stored in CATIA database

-- Component and Load Case Libraries include pre-defined elements such as springs, bushings, tires, steering maneuvers, braking maneuvers, and suspension testing for use in CATIA models

-- Apply control systems to CATIA mechanical assemblies

-- Industry standard suspension postprocessing

PolyFEM 3.0 - Structural analysis in CATIA enhanced features:

-- Optimization and Sensitivity - automatically obtain the optimum value of multiple design parameters for goals of performance, cost, weight, etc.

-- Out-of-Core Solver - new solver improves solution speed for large models

-- Performance Options - improve solution speed with two options: adaptive p-escalation and relaxing convergence tolerance for the iterative solver

-- Automatic Mesher Enhancements - improved mesh quality, better handling of geometry errors and reduced memory usage

-- New Viewer - uses GL and OpenGL, display of line, point, isosurface contours and improved dynamic view navigation
