MANUAL COSMOSWORKS PDF

Software's new features and performance upgrades let designers perform high-powered analysis 10 to 15 times faster than ever before. SolidWorks today put sophisticated design analysis within the reach of every designer with major upgrades to its COSMOS analysis applications. Performance upgrades that enable solvers to use processor cycles more efficiently make the COSMOS family anywhere from 10 to 15 times faster than comparable analysis applications. The applications' speed and automated simplicity enable users to focus on perfecting designs with ongoing analysis throughout the design process. More than 10, companies currently use COSMOS products to reduce their prototyping costs and cut time-to-market by producing accurate designs faster than the competition. COSMOSWorks enables users to test assemblies' behaviors without the complicated and time-consuming step of fully modeling component connectors - such as pins and springs - up front.

The program includes modules to solve linear and nonlinear static and dynamic structural problems, in addition to problems of heat transfer, fluid mechanics, electromagnetics and optimization.

Modules for such special analysis options as fatigue are also available. The system is constantly developed and maintained by using state-of-the-art techniques and up-to-date hardware capabilities. The program is completely modular allowing you to acquire and load only the modules that you need. It is an interactive full three-dimensional CAD-like graphic geometric modeler, mesh generator and FEA pre- and postprocessor.

You can create the geometric model, mesh it, provide all analysis related information, perform the desired type of analysis, review, plot and print the results, without having to leave the GEOSTAR screen.

The program is powerful, intuitive, and easy to learn and use. The average user can learn, create and solve real life problems after few hours of training. Chapter 1 Introduction Figure A diverse set of geometric modeling capabilities combined with flexible meshing options allow for the creation and meshing of complex models with ease.

Loading, boundary, and initial conditions can conveniently be applied in association with geometric entities and in any defined coordinate system. More information on the various aspects of this module are given in Chapter 3. Commands are grouped in an intuitive way that makes it easy to select and issue the proper command to perform the desired function.

Once a command is issued, you will be guided by dialog boxes throughout the input process. Default entries are used where appropriate. The Geo Panel window provides toolbars and buttons for quick access to commonly used commands. Items and dialog boxes and prompts list all possible entries. Error messages are issued in a simple and direct manner.

Many listing commands are available to inform you on the status of the database. This function can help you generate reports. GEOSTAR's comprehensive list of geometry-related commands makes it possible to quickly and accurately create, modify, list, delete, undelete, pick and identify geometric entities. These entities can be combined and used to create complex models. Nonlinear structural analysis isbeing added. Mesh Generation Mesh generation is simple and powerful through commands dealing with one, two, and three dimensional models.

Meshing commands operate on predefined geometric entities to create a finite element mesh. The degree of control over the meshing process is determined by the user through a variety of commands. Complex multi-connected regions, in particular, can be easily meshed using the contour and region entities.

Mesh density can be fully controlled throughout the model. To further simplify the modeling and meshing of complex problems, the bond feature can be used to mesh different parts of the model separately, even using different types of elements if necessary, and then bond them together for analysis. Loads and Boundary Conditions Loads and boundary conditions can be directly applied to nodes or elements or indirectly through association with geometric entities.

This feature simplifies the process and minimizes the required input time. Loads and boundary conditions should be applied after meshing. Adaptive Meshing Adaptive meshing using the H-method provides you with automatic mesh refinement at the areas of stress concentration to evaluate and improve the accuracy of results for linear static analysis problems. The P-method internally uses a higher polynomial order instead of creating additional nodes to improve the accuracy.

An option to combine the H and P methods is also available. With these features, you can build application programs to automatically construct and analyze designs using sophisticated programming functions. Selection Lists A selection list is a filtered set of the members of an entity. Once activated, the selection list allows you to operate only on the selected members of that entity. Access will be denied to other members of the entity not included in the list.

Various ways to add to or take away from selection lists are provided. A facility to perform set operations like union and intersection is provided for selection lists.

The created windows can be easily manipulated for convenient viewing while developing or processing the model. Many commands include graphics and procedures to illustrate their functions. Links to related commands are also provided. This file called the session file provides a backup in case of problems with the database. Geometric Format Recreation of a model from the session file can take a long time due to the fact that it contains intermediate steps that do not contribute to the final state of the model.

The geometric format ignores such intermediate steps by operating directly on the database. The geometric or neutral format is a special format in which the equation of the related entity is represented. In addition to saving time, this utility is useful in combining independently created parts of a model. Result Evaluation Once an analysis is performed, the user can proceed to evaluate the results. The postprocessing capabilities include graphic and text displays of results.

Line, colorfilled contour, vector plots, isoplane and section plots can be generated for various result quantities in the different modules. Animation is also provided for structural deformations, mode shapes, stresses, strains and many other response quantities. In addition, a utility for time-history or XY type plots is available.
