Motivation for Using Adams/Car (Cont.)

7. S1-7 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation MacPherson SLA Motivation for Using Adams/Car (Cont.) ● Facilitates quick subsystem changes ● You can easily replace one subsystem without changing any other part of the vehicle.

8. S1-8 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation Motivation for Using Adams/Car (Cont.) ● Templates ● Allow you to tailor one system for multiple vehicles.

9. S1-9 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation ● Within the Adams/Car configuration file (acar.cfg and.acar.cfg), the particular application of Adams/Car is specified as either standard user mode or expert user mode. ● Expert user (Template Builder and Standard Interface) ● Allows creation of building-block of Adams/Car, templates, with access to Template Builder ● For experienced Adams users ● Access to all Adams modeling entities ● Standard user (Standard Interface only) ● Specifically for designers and testing engineers ● Use libraries from the Adams/Car database to easily create vehicle (sub)assemblies ● Simulation environment tailored to automotive standards User Modes

10. S1-10 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation  Three types of databases:  Shared - Common to all users, provided by MSC.Software with example files  Private - User workspace (created by Adams/Car in your $HOME directory)  User - User/site specific ● A database is a collection of tables (directories) stored on the hard drive. The top directory, which has the extension.cdb, stores a number of tables (directories). Each table is a placeholder for model information. Database Structure—A Directory Hierarchy

11. S1-11 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation ● The databases are defined in private.acar.cfg or common acar.cfg ● No limitations on number of databases ● Each project should have a separate database ● You can only save to one database at a time ● For more information about managing Adams/Car databases, see the Adams/Car online help. Database Structure—A Directory Hierarchy (Cont.)

12. S1-12 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation ● Adams/Car divides your suspension or full-vehicle model into subsystems and components so you can manage the data more easily. It saves these components into an Adams/Car database. The ultimate goal is to build.adm files and produce results, which are stored in the working directory. ● You can set up the database that stores the components that build up the model, and so on, using the database management tools (Tools  Database Management). ● Adams/Car saves your.adm,.acf, and results to your working directory (File  Select Directory). Saving Files: Working Directory Versus Database

13. S1-13 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation Configuration Files ● Configuration files contain information that Adams/Car reads during startup to correctly initialize the session: ● User mode (expert versus standard) ● Personal databases and tables ● Default property files ● Default writable database ● Database search order ● Orientation of global reference frame ● Other preferences

14. S1-14 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation For more information about configuration files, see the Adams/Car online help. Configuration Files (Cont.)

15. S1-15 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation Configuration Files (Cont.) ● Shared versus private configuration files ● Adams/Car uses two configuration files: ● Shared configuration file (acar.cfg) - Is a common file that sets up default parameters (read first). Can be a specially created site-specific file. This file is located in the /acar directory (where is the path to your Adams installation directory). ● Private configuration file (.acar.cfg - note the period at the front) - Is a private file that also sets up parameters, but takes precedence over the common acar.cfg file (read second). The private configuration file is located in the HOME directory (environment variable). ● Having both configuration files allows users on a network to work from default parameters and to customize their own workstations with the private.acar.cfg file.

16. S1-16 ADM740, Section 1, June 2007 Copyright  2007 MSC.Software Corporation Configuration Files (Cont.) ● Saving configuration files ● You can save your configuration files as follows: ● Shared configuration file (acar.cfg) - Manually open the file in a text editor and save it. This file is located in the /acar directory (where is the path to your Adams installation directory). You typically do not edit this file unless you are making a site-specific configuration file. ● Private configuration file (.acar.cfg) - Use Settings  Save A/Car Configuration.
