IntroductionCOSMOSWorks is a design analysis automation application fully integrated with SolidWorks. This software uses the Finite Element Method (FEM) to simulate the working conditions of your designs and predict their behavior. FEM requires the solution of large systems of equations. Powered by fast solvers, COSMOSWorks makes it possible for designers to quickly check the integrity of their designs and search for the optimum solution. COSMOSWorks comes in several bundles to satisfy your analysis needs. It shortens time to market by testing your designs on the computer instead of expensive and time-consuming field tests. COSMOSMotion lets you make sure your assembly mechanisms will work before you build them. Fully embedded inside of SolidWorks, COSMOSMotion enables engineers to size motors/actuators, determine power consumption, layout linkages, develop cams, understand gear drives, size springs/dampers, and determine how contacting parts behave. COSMOSFloWorks combines a high level of functionality and accuracy with ease-of-use. Fully embedded inside of SolidWorks, COSMOSFloWorks is perfect for the engineer who needs flow analysis, but is not necessarily an expert in the field of fluid simulation. Whether you are developing an automobile, the wing of an airplane, or an exhaust valve, using COSMOSFloWorks in the product development cycle can help you build a better product in less time.

About this BookThis book helps you get started with the COSMOS software. Chapter 1, Installation, provides the basic installation steps and additional links to other documents with further instructions. Chapter 2, Resources for Learning, introduces you to the many resources available to help you learn about the COSMOS software. Chapter 3, Whats New in COSMOSWorks 2005, provides the highlights of the new functionality in the COSMOSWorks software. Chapter 4, Whats New in COSMOSMotion 2005, provides the highlights of the new functionality in the COSMOSMotion software. Chapter 5, Whats New in COSMOSFloWorks 2005, provides the highlights of the new functionality in the COSMOSFloWorks software.

1InstallationIntroductionThis chapter describes how to install the COSMOSWorks application and related products using Microsoft Windows Installer (WI) technology. The following sections serve different installation types: Section 1: describes tasks that the typical COSMOSWorks user performs - the installation, modification, and removal of the COSMOSWorks application. Section 2: describes tasks that a system administrator performs - the creation of administrative images on a server machine. Section 3: describes how a system administrator can install and manage the COSMOS license service on a server machine. Section 4: describes tasks that allow for silent installations of COSMOS products.

Notes:COSMOSWorks, COSMOSMotion, and COSMOSFloWorks are add-ins to SolidWorks. After installing an application, you can enable or disable it by clicking Tools, Add-In. This chapter is a guide to installing the COSMOSWorks application using WI. It is not intended to be an exhaustive discussion of the WI technology. For more information on WI, see Microsofts Windows Installer documentation. The WI term, administrative image, is analogous to the InstallShield term, server installation. SolidWorks 2005 SP0.0 or later must be installed on your computer before attempting to install COSMOSWorks 2005. The installation of COSMOSWorks interface is required for all COSMOSWorks bundles and add-on options except COSMOSFloWorks, COSMOSMotion and COSMOSEMS.

Chapter 1 Installation

Section 1: For the Typical COSMOSWorks UserInstallation typesYou can install the COSMOSWorks application using one of the following methods: Individual installation of the COSMOSWorks application files on the user's computer. The COSMOSWorks application is installed directly on the local hard drive. This installation takes up disk space on the user's computer and must be updated locally when a new service pack is available. However, executing the program is faster because it is not impacted by network traffic. Client installation on the user's computer that references the COSMOSWorks application files on a remote server. The COSMOSWorks application files are not copied to the client computer, but an installation is performed to configure the license if necessary and create the registry entries, shortcuts etc. The user runs the COSMOSWorks application over the network using an administrative image on a remote server. This saves disk space on the local computer, but program execution is slower with higher network traffic. The client installation can only be performed from an administrative image. Refer to the To install on a local computer from an administrative image section for more details. COSMOSMotion, COSMOSFloWorks and COSMOSDesignSTAR programs cannot reference files from a remote machine. Thus the client installation for these products copies all the program files locally on the client machine similar to an individual install.

The Installation SourceYou can install COSMOSWorks and other COSMOS applications in one of two ways: From a COSMOSWorks CD. From the administrative image on a server across a network. Your system administrator must create the administrative image and inform you of its location. To install on a local computer from the CD: 1 Insert the COSMOSWorks Disk into your CD-ROM drive. The setup program starts automatically. Read the Welcome message and click Next. The Software License Agreement window appears.

2 Read the agreement and choose I accept the license agreement then click Next. Otherwise, click Cancel to exit the installation program. If you click Next, the COSMOS License Information window appears. 3 Follow on-screen instructions to copy program files and configure your license. Use the Installation Tips below for any questions during installation. You may need to reboot your computer when the installation is complete.

Chapter 1 Installation

To install on a local computer from an administrative image: 1 Using Windows Explorer on your local machine, map the network drive where the administrative image of COSMOSWorks is installed. Ask your system administrator for this location. 2 Double-click the COSMOSSetup.exe file located in the drive mapped in the above step. Use the following installation tips for any questions during installation. You may need to reboot your computer when the installation is completed.

1-4

Getting Started with COSMOS

Running the COSMOSWorks ApplicationIn your Windows desktop, click Start, Programs, COSMOS 2005 Applications, COSMOSWorks 2005. You can similarly launch other COSMOS products like COSMOSMotion, COSMOSFloWorks, COSMOSDesignSTAR, and COSMOSM.

Modifying, Repairing, or Removing an Installation1 In Windows, click Start, Settings, Control Panel. 2 Double-click Add/Remove Programs. The Add/Remove Programs dialog box appears. 3 Select the appropriate COSMOS product, for example COSMOSWorks 2005. 4 Based on your operating system, click the appropriate button to modify or delete the installation. If you are modifying an installation, go to step 5; otherwise, confirm to delete the installation. The Setup dialog box appears. 5 Click Next. 6 In the Program Maintenance dialog box, select one of the following options: Modify. This option simply reinstalls the application files. It is rarely used. Repair. To reinstall COSMOSWorks using the current installation parameters. The Repair option is useful if the COSMOSWorks installation is corrupt. Follow the on-screen instructions to repair the installation. Remove. To completely remove the COSMOSWorks application. Follow the on-screen instructions to remove the application.

Section 2: For System AdministratorsThe following topics address the needs of system administrators: Creating an administrative image of the COSMOSWorks installation on a server machine. Removing an administrative image.
