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.

Installation

Introduction

This 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 Microsoft’s 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 User

Installation 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 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.

• 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.

Removing an administrative image.

1-5


Creating an Administrative ImageTo serve the COSMOSWorks application files across a network, you create an administrative image of the COSMOSWorks application files on the server's hard drive. You can install the administrative image from any computer on the network. Browse the network for the location on the computer that will act as the server for the COSMOSWorks application. You can create an administrative image on the client computer by specifying a folder on its local hard drive.

The resulting administrative image is a tree of folders that contains all the distributed files in an uncompressed format. The administrative image occupies a large amount of space on the server's hard drive. Once the administrative image is created, you can start additional installations on other computers in the network from this server location.

Client computers can access the administrative image to run the COSMOSWorks application on their local computers. You must perform a client installation on each client computer before it can access and use the COSMOSWorks application on the server.

To create an administrative image:1 Insert the COSMOSWorks CD into your CD-ROM drive.

2 In your Windows desktop, click Start, Programs, Accessories, Command Prompt.

3 In the Command Prompt window, enter:

msiexec /a <Msi_ path>

Upgrading an Administrative ImageThe following procedure applies when you upgrade to major COSMOSWorks releases. For information on how to upgrade an administrative image for a COSMOSWorks service pack, refer to the Download and Installation section of each service pack page.

To upgrade an administrative image:1 Create an administrative image on a server for COSMOSWorks 2005 using

the previous procedure, “To create an administrative image”.

2 Install COSMOSWorks 2005 and other COSMOS products on each client computer using the procedure “To install on a local computer from an administrative image”.

Removing an Administrative Image

To remove an administrative image from the server:1 Make sure that no active COSMOSWorks sessions are in progress.

2 Make sure that COSMOSWorks and other COSMOS products are uninstalled from all the client machines on which it was installed.

3 Delete the administrative image from the server’s hard drive.

Section 3: To Install and Configure the COSMOS License Service

The COSMOS Network License Manager installation allows you to install only the license files as well as to configure the COSMOS License Service on a server machine. You cannot run COSMOS on the server machine using this installation. However, you can install COSMOS on any client computer across the network using the procedure, “To install on a local computer from CD“ or “to install on a local computer from an administrative image” described in the previous sections. During the client installation, you can specify to access the license from the server machine using the port-number@host-name option in the COSMOS License Information dialog box.

To install the COSMOS Network License Manager:1 Insert the COSMOSWorks CD into your CD-ROM drive.

2 From the CD menu, choose the second button “Install COSMOS Network License Manager”. The Installation starts up.

NOTE: When the COSMOSWorks 2005 Install Choice dialog box appears, select Upgrade an existing installation.

You can use the COSMOS License Administrator located under Start->Programs-> COSMOS Network License Manager; to check or reconfigure your license based on the license file. If you do not have a license file, the COSMOS License Administrator lets you request it through the Internet.

Section 4: Silent Installations

Passing Properties to a Silent InstallationTo start a silent installation (without the display of a user interface or dialog boxes), use the /i and /qn options of the msiexec.exe command. Set the global properties for installation options different from defaults.

Examples

Suppose that your computer has the following options:

• Installation source pointing to the msi file package

<CD drive letter>:\cwwi\MainInstall\COSMOSWorks\i386_

COSMOSWorks_English.msi

• English language operating system

• At location C:\Program Files\<your_preferred_folder>

• Location of SolidWorks application C:\Program Files\<SolidWorks_folder>

To perform an individual installation of COSMOSWorks from the COSMOSWorks CD on this computer, enter the following command:

msiexec /i “<CD drive letter>:\cwwi\MainInstall\COSMOSWorks

\i386_COSMOSWorks_English.msi” INSTALLDIR= “C:\Program Files\<your_chosen_folder>” SOLIDWORKSPATH=

“C:\Program Files\<SolidWorks folder>” SWDISTSUBTYPE=0

LICENSEFILEPATH = “<folder_path \license.dat” /qn

The msi package name contains the language as well as the product name to be installed and is constructed as i386_<productname>_<language>.msi. For example if you were to install the French version of COSMOSWorks, then the path to the msi installation package would be as follows:

NOTE: If you do not have the license file, then do not pass the property LICENSEFILEPATH in the command line options.

5-1

Chapter 5 What’s New in COSMOSFloWorks 2005

Expanded Flow Features

Fully Transparent Bodies for Radiation

COSMOSFloWorks 2005 can simulate heat radiation passing through bodies. It is assumed that the body that is transparent to radiation does not participate in the radiation heat transfer (i.e., neither emits nor absorbs heat radiation) and exchanges the heat by convection and conduction only. This functionality helps users save time in analysis by choosing to neglect the surfaces that are not important for radiation heat transfer.

Solar Radiation Dependent on TimePE

In COSMOSFloWorks 2005, both the intensity and direction of solar radiation can be dependent on time. This functionality allows users to solve real life problems involving directional radiation changing in time (e.g., the heat generated by the sun during a day).

Dynamic Preview of Section PlotsCOSMOSFloWorks 2005 allows users to dynamically preview section plots. Users can refresh section plot immediately after they change the plot definition, e.g. change the section plane or plane position, add vectors, change region, etc.

5-2


Estimate Flow and Heat Transfer Parameters for a Body

COSMOSFloWorks 2005 now allows the user to obtain values such as Heat Flow, Shear Force, Min/Max Temperature, etc. for each body. This functionality gives users a better understanding of specific results like the maximum temperature, total shear force, etc. in a body.

Automatic Setting of Fully Developed Profile at Inlets

COSMOSFloWorks 2005 automatically computes the velocity profile and turbulent parameters based on whether the inlet flow is fully developed or not. This functionality makes it easier for users to simulate real life problems that require a fully developed velocity profile on inlets. It also eliminates the need to extend the pipe in order to provide adequate length for developing the profile thereby reducing computational resources.

View 3D Profile on a Section PlotCOSMOSFloWorks 2005 allows users to visualize 3D profile of velocity, temperature, etc on a section plot. 3D plots help to interpret and understand the analysis results better.

5-3


New Vorticity PlotUsers can now plot the vorticity parameter in COSMOSFloWorks 2005. The new parameter allows the user to visualize how the flow is swirling. This offers users a better understanding of results for swirling flow applications.

Parametric Study ToolPE

Parametric study in COSMOSFloWorks 2005 is a tool designed to automatically perform a set of calculations varied only by a selected parameter (a particular model dimension or a boundary condition) in order to find a configuration where the flow parameter of interest matches the predefined target value. This functionality helps users reduce the effort to conduct what-if scenarios. It also makes it easier for the users to find the best configuration for the problem under consideration.

5-4


Improved Usability

Simultaneous Edit of Multiple Input Values

COSMOSFloWorks 2005 allows users to view and edit common properties of pre-processor features across several projects simultaneously. This helps users save time to setup the problem when exploring multiple what-if scenarios.

Equation Goals Tied to Boundary Conditions

Equation goal in COSMOSFloWorks 2005 can now be a function of parameter values specified as boundary conditions, initial conditions, heat sources, etc. This makes it easier for the user to specify parameters of interest as an equation goal. With the help of this functionality, you do not need to type these values manually any more, instead you simply select the necessary condition.

Automatic Detection of Fluid Volume to Apply Initial Condition

When applying fluid initial conditions to a volume, the user can just select any of the volume’s boundary surfaces and COSMOSFloWorks 2005 automatically detects the inner fluid volume. Using this functionality, there is no need to create auxiliary bodies to define initial condition to fluid volume. This helps users save considerable time and effort.

5-5


Creation of Multiple Goals for One Selected Object

COSMOSFloWorks 2005 allows the user to specify several goals for the same reference object (face or volume) at once. This makes it easier to setup problems where the user needs to specify several goals to the same selected face or volume.

Copy Features among ProjectsCOSMOSFloWorks 2005 allows the user to copy a feature into several projects. Users can copy a new input from a project to several projects making it easier and faster to setup multiple What-If scenarios.

New Selection FilterCOSMOSFloWorks 2005 has a new selection filter that allows the user to remove faces of a specific type from the selection list. For example, to select only inner faces of an internal model, you can select the component, then use the filter to remove all external faces. This makes it easier for the user to specify boundary conditions on specific type of faces like interior faces, exterior faces etc.

5-6


Moveable Color ChartCOSMOSFloWorks 2005 allows users to dynamically move the color chart across the graphics area. Most often for better viewing of results it is convenient to be able to move the color chart across the screen. Dynamic moving of the color chart makes this possible.

Automatic Definition of Reference Coordinate System

COSMOSFloWorks 2005 automatically defines a coordinate system (CS) associated with a face while defining boundary conditions which requires a reference CS. Users do not need to anymore create CS to apply boundary conditions. This functionality provides a convenient and easier way to define boundary conditions like swirl referenced to the coordinate system of the face they are applied.

Improved Graphical Visualization of Boundary Conditions

COSMOSFloWorks 2005 now displays symbols for symmetry plane, solar radiation, etc. This functionality provides better visualization of applied BC’s. It also gives the user an insight into the direction of solar radiation.

5-7


Customized Saving of PlotsCOSMOSFloWorks 2005 allows users to create pre-defined plots (section plots, iso plots etc) and automatically save them as image files once the analysis is completed. This functionality allows automatic creation of analysis result images. You can use these automatically created plots to generate analysis reports.

Plot Normal and Tangential Velocities

COSMOSFloWorks 2005 allows users to plot the normal and tangential velocity. Normal and tangential velocity plots help in better understanding of results for rotational flow problems.

Complete Input Data Report During Solving

COSMOSFloWorks 2005 makes the complete input data available on the screen during the calculation process. If mistakes are found in the input then the user can immediately correct them and restart the calculations.

5-8


Automatic Report and Goal PlotOnce the analysis is completed, COSMOSFloWorks 2005 allows users to automatically create custom reports and goal plots. This functionality speeds up the task of creating custom analysis reports. It also allows users to create reports for several projects and then use them to compare the results.

Improved Performance

Improved Algorithm for Automatic Solver Termination

A new algorithm has been implemented in COSMOSFloWorks 2005 to stop the solver once convergence has been achieved. In prior versions the solver continues for a while after convergence is achieved. In COSMOSFloWorks 2005 the solver is terminated as soon as convergence is achieved thereby reducing the calculation time.

Postprocessor AccelerationIn COSMOSFloWorks 2005 the time taken for result visualization has been reduced. This saves you time and allows faster export of trajectory track data.

5-9


Improved Calculations for Transient AnalysisPE

In COSMOSFloWorks 2005 the manual time step for a transient analysis can now depend on the time and it adapts with the progress of solution. This functionality allows faster solution of time-dependent problems that have regimes with very different characteristic times.

Refine Certain Cell Type in the Entire Computational Domain

In COSMOSFloWorks 2005 users can select a particular cell type (fluid cells, partial cells etc.) and then choose to refine them over the entire computational domain. In previous versions users could only refine cells locally. This functionality enhances the mesh control feature and helps achieve faster convergence over the entire domain.

Extract Computational Mesh from Results File

COSMOSFloWorks 2005 can export computational mesh from the calculated results. It is useful if the problem’s initial mesh is optimized during the calculation and you want to start a new calculation with the optimum mesh settings. This results in better accuracy and faster convergence.

5-10


Accelerate Particle TracingParticle Study Tool in COSMOSFloWorks 2005 allows users to save particle data in the result file reducing the time taken to generate particle tracing. The tool also allows you to specify a wall interaction model for a specific wall. This allows for faster generation of particle tracking results and accelerates data access in case of a large number of particles.
