CADSI Announces the Release of CATDADS 9.0 and New CATIA Elfini Interface.CORAVILLE, Iowa--(BUSINESS WIRE)--June 17, 1998--CADSI(R) (Computer Aided Design (application) Computer Aided Design - (CAD) The part of CAE concerning the drawing or physical layout steps of engineering design. Often found in the phrase "CAD/CAM" for ".. manufacturing". Software Inc.) announces the release of CATDADS(TM) version 9.0 for design simulation embedded in CATIA A family of 2D and 3D CAD programs from IBM. CATIA was one of the first CAD programs to provide 3D solid modeling. The program was developed by Dassault Systems, a French aerospace company. (R) and a CATIA Elfini interface for flexible mechanical simulation. These products will be available August 1 on supported UNIX UNIX Operating system for digital computers, developed by Ken Thompson of Bell Laboratories in 1969. It was initially designed for a single user (the name was a pun on the earlier operating system Multics). platforms. As one of the first companies in the CAA Caa See CCC. (CATIA Application Architecture) Strategic Development Partner program, CADSI CADSI Canadian Association of Defence & Security Industries CADSI Communication and Data Systems Integration CADSI Communications and Data Systems Integration has worked closely with Dassault Systemes Dassault Systemes (Dassault Systèmes S.A.) (Pronounced - Dasoh) (NASDAQ: DASTY; Euronext: 13065) is a leading company specializing in 3D and PLM (Product Lifecycle Management) software. to create seamlessly integrated applications using CATIA development tools. The most recent result of this development partnership is CATDADS 9.0 and the CATIA Elfini interface. The latest enhancements to CATDADS 9.0 empower mechanical engineers to analyze real-world behavior of mechanical systems directly in CATIA. Simulation results are easily viewed as graphs and animation to verify fit, performance, and reliability of product designs before building a single physical prototype. "CADSI's strategic partnerships with Dassault Systemes and key CATIA accounts has resulted in significant new functionality in CATDADS 9.0 including a new CATIA Elfini module. The interface with Elfini allows CATDADS users to easily incorporate elasticity information calculated in Elfini for flexible component simulation," says David Bird, CADSI's V. P. of Marketing and Business Development. "By testing their products in CATDADS, manufacturing companies are able to reduce physical prototypes, increase product quality, and shorten time to market." "We are very pleased that the integration with the CATIA Elfini finite element See FEA. solver will now benefit all CATDADS customers," says Gerard Lecina, Director Analysis and Simulation Division, Dassault Systemes. "This integration is a result of the CAA Strategic Development Partnership established with CADSI, and enables true flexible body simulation in the CATIA environment." A summary of key CATDADS enhancements follows: CATDADS 9.0 New Module -- CATIA Elfini Interface - this module is used to perform flexible body analysis with CATDADS using the Dassault FEA (Finite Element Analysis) A mathematical technique for analyzing stress, which breaks down a physical structure into substructures called "finite elements." The finite elements and their interrelationships are converted into equation form and solved mathematically. software, Elfini. This powerful capability allows direct import of flexibility data including the mass matrix, stiffness matrix and modes shapes calculated in Elfini into CATDADS for flexible component simulation. Implicit Integrator -- The implicit integrator may increase the solution speed by a factor of five or more for mechanical systems that contain very high numerical damping or high frequency numerical "noise" such as those due to beam or bushing force elements. Additional Driver Constraints -- Screw joint (rotational or translational) -- Using parametric curves defined in CATIA, the following joint drivers are available: - Point-curve (drive a body along another curved body) - Roll-curve (given two curved bodies touching, roll either body along the other) Enhanced Friction Modeling -- Stiction (STatic frICTION) A type of hard disk failure in which the read/write heads stick to the platters. The lubricant used on certain drives heats up and liquifies. When the disk is turned off, it cools down and can become like a glue. (lock-up) and dynamic coefficients of friction are incorporated in the following elements: cylindrical, universal, screw, spherical, planar -- Using parametric curves defined in CATIA, friction is available with the following joints: - Point-curve, point-surface, slide-curve - One coefficient of friction coefficient of friction n. pl. coefficients of friction The ratio of the force that maintains contact between an object and a surface and the frictional force that resists the motion of the object. is defined for all relevant DOFs - When one DOF See depth of field and 6DOF. DOF - degrees of freedom senses stictions or lock-up, all DOFs are then locked Interactive Simulation -- The ability to stop and restart a CATDADS simulation at any time step, allowing the user to change mass properties The Mass Properties of an object are its:
elements, and the type and direction of a driving constraint. Improvements in Redundant Constraint Handling -- Makes the modeling process more automatic and allows the user to spend more time doing analysis and less time "tweaking tweaking Vox populi Fine-tuning to produce optimal results " the model's joints in preparation for simulation.
