COSMOSDesignSTAR 4.0 to Be Unveiled at NDES

National Design Engineering 2003

Latest Innovations and Enhancements Bring Associative Analysis Capabilities to Autodesk Inventor, Solid Edge and SolidWorks Users to
Help Them Simulate Real-World Operating Conditions

LOS ANGELES--(BUSINESS WIRE)--March 3, 2003-- COSMOS today announced that the eagerly anticipated new release of COSMOSDesignSTAR will be demonstrated at the National Design Engineering Show in Chicago, March 3-6, 2003, in Booth #7007. COSMOSDesignSTAR, a multi-CAD design analysis tool, allows designers and engineers to quickly detect potential design problems and fix them before prototype production begins so companies don't have to spend time and money fixing post-production errors. By being able to conduct multiple "what if" scenarios, designers can quickly determine the reliability of their products, shorten design review cycles and reduce the number of expensive physical prototypes.

Unique Insight Into the Real-World Behavior of Solid Models

COSMOSDesignSTAR 4.0 allows designers to analyze the overall structural integrity of their parts and assemblies. Fully associative with Autodesk Inventor, Solid Edge and SolidWorks, COSMOSDesignSTAR 4.0 can also read geometry files from a number of other popular solid modeling programs, including Pro/Engineer, CADKEY and IDEAS.

COSMOSDesignSTAR 4.0 introduces major improvements in ease of use and analysis automation. It showcases new analysis functionality and numerous customer enhancements.

Automatic Mesh Tools

For those engineers who are not analysis experts, COSMOSDesignSTAR 4.0 includes a number of new tools to help even novice users successfully mesh and analyze complex parts and assemblies:

-- A mesh failure diagnostic tool to identify possible problems with the model and offer solutions to those problems;
-- Controls for easily meshing parts in complicated assemblies, especially those with large size differences between the parts;
-- Automatically attempting to mesh the model with a different element size in case the mesh fails on the first pass, with user controlled inputs on the number of attempts and the change in element size.

New Sketcher Interface to Define/Modify the Geometry

In addition to numerous analysis enhancements, COSMOSDesignSTAR 4.0 also features a new sketcher tool allowing users to create their own 2D profile or cross section. The sketching feature allows engineers to make simple part geometry changes directly within the COSMOSDesignSTAR interface. COSMOSDesignSTAR 4.0 sketcher tool paves the way for introducing 2D analysis on 3D CAD models, saving time and computational resources:

-- Projecting the defined 2D section onto the 3D CAD models,

without having to toggle back and forth between the CAD and

analysis programs;

-- Create 2D surfaces out of the sketches.

2D Analysis

COSMOSDesignSTAR 4.0 puts more power into the designers' hands by allowing them to simplify the analysis done on certain 3D CAD models like thin and thick extrusions, and solids with an axis of revolution. With COSMOSDesignSTAR 4.0, it is possible to break down such a 3D model into a two-dimensional planar body representation. New elements to support such 2D analysis capabilities have been incorporated. The 2D element features greatly reduce analysis solution time by more efficiently using computer resources.

Loads/Assembly Contact Conditions

COSMOSDesignSTAR 4.0 introduces new capabilities in the area of loads/assembly contact conditions, providing greater flexibility for designers to mimic the real-world conditions as well as reduce modeling time:

-- Remote loads, which allow the user to ignore certain

components in the assembly and yet consider their effects on

the rest of the assembly;

-- Rigid connection that allows one or more faces of one

component to move rigidly with respect to one or more faces of

another component in the assembly;

-- Shrink fitting that simulates the effect of fitting one

component inside a slightly smaller cavity;

-- Thermal contact resistance that eliminates the need to model

very thin layers of material between two parts, thereby saving

meshing and analysis time.

Results Visualization Tools

COSMOSDesignSTAR 4.0 includes nearly 100 customer requested enhancements, including multiple options for visual feedback to help interpret the analysis results and improve analysis reports. Some of these enhancements include:

-- Exploding individual parts of an assembly (move, rotate,

enlarge, shrink) to conveniently define loads and boundary

conditions as well as to view results plots;

-- Superimpose the deformed shape over the original model with

different levels of transparency;

-- Show maximum and minimum value annotation that helps in

identifying the critical areas of the model;

-- Section and Iso plot transparency;

-- Customizable legends in plots: Position, number format, plot

title, etc. can be customized for individual plots;

-- Many more results visualization enhancements.

All of these features allow users to share and disseminate visual analysis data more easily with clients and co-workers.
