Introduction Chapter One

Training Manual Introduction February 2, 2004 Inventory # Welcome! Welcome to the ANSYS Workbench introductory training course for Design Simulation! This training course covers the basics of using Design Simulation in performing structural and thermal analyses. It is intended for all new or occasional Design Simulation users, regardless of the CAD software used. –Although some aspects of interfacing with ANSYS will be covered, this course is not intended for users wishing to work primarily in the traditional ANSYS environment. Those users should consider taking Introduction to ANSYS Parts 1 and 2 Training courses. –This course covers the Design Simulation module of ANSYS Workbench. The DesignModeler and DesignXplorer modules of ANSYS Workbench are covered in separate classes.

Training Manual Introduction February 2, 2004 Inventory # Course Objectives To teach the basics of using Design Simulation in the following areas: –General understanding of the user interface, as related to geometry import, meshing, application of loads and supports, and postprocessing –Procedure for performing FEA simulations, including linear static, modal, and harmonic structural analyses and nonlinear steady-state thermal analyses –Utilizing parameters for ‘what-if’ scenarios –Interfacing with the ANSYS solver for more advanced functionality

Training Manual Introduction February 2, 2004 Inventory # B. ANSYS Workbench Overview What is ANSYS Workbench? –ANSYS Workbench is a new-generation solution from ANSYS that provides powerful methods for interacting with the ANSYS solver functionality. This environment provides a unique integration with CAD systems, and your design process, enabling the best CAE results. ANSYS Workbench is comprised of four modules: –Design Simulation for performing structural and thermal analyses using the ANSYS solver –DesignModeler for creating and modifying CAD geometry to prepare the solid model for analysis –DesignXplorer and DesignXplorer VT for investigating the effect of variations input (e.g., geometry, loading) to the response of the system (e.g., stress, frequency) –FE Modeler for translating meshes from an Nastran bulk data deck for use in ANSYS

Training Manual Introduction February 2, 2004 Inventory # … Design Simulation Overview Analysis types available in Design Simulation: † –Linear Stress: Determines deflections, stresses, factors of safety, etc. based on standard strength of materials concepts under static loading –Modal: Determines natural frequencies of a system (free vibration), including the effects of loading on a pre- stressed structure. –Heat Transfer: Steady-state thermal analyses to solve for temperature field and heat flux. Temperature-dependent conductivity and convection allowed. Thermal-stress analysis supported as well. † The list here reflects analysis capabilities possible within the Design Simulation GUI. Note, however, that the ANSYS license used dictates what functionality is available to the user.

Training Manual Introduction February 2, 2004 Inventory # … Design Simulation Overview Analysis types supported by Design Simulation (cont’d): † –Harmonic: Determines structural response of system under sinusoidal excitation as a function of frequency. –Linear Buckling: Determines failure load or safety factor for buckling and its buckling mode shapes. –Shape Optimization: Indicates areas of possible volume reduction based on load paths through the part using Topological Optimization technology. –Nonlinear Structural: Calculates deflections and stresses of system under static loading, accounting for large deflection effects and contact nonlinearities (and material nonlinearities). † The list here reflects analysis capabilities possible within the Design Simulation GUI. Note, however, that the ANSYS license used dictates what functionality is available to the user.

Training Manual Introduction February 2, 2004 Inventory # … Design Simulation Overview The user can also access regular ANSYS functionality not otherwise directly accessible from within Design Simulation –The Preprocessing and Postprocessing Command Builders allow users to stay in the Design Simulation environment but access advanced pre- and post- processing features. The information is stored in a “branch” and is reused for each analysis. –The mesh and loads can also be transferred to regular ANSYS easily for further modeling, useful for users comfortable in the regular ANSYS environment (Both advanced topics will be covered later)

Training Manual Introduction February 2, 2004 Inventory # C. Starting Design Simulation There are two methods of launching Design Simulation: –From within ANSYS Workbench –Directly from CAD system Because it is very useful for most users to understand that Design Simulation is a module within ANSYS Workbench, the basics of Workbench and project management will be discussed first. Afterwards, launching Design Simulation directly from a supported CAD system will be covered.

Training Manual Introduction February 2, 2004 Inventory # … Launching ANSYS Workbench Starting ANSYS Workbench: –Workbench modules are all launched from one icon, “ANSYS Workbench,” under “Start Menu > Programs > ANSYS 8.0” –Alternatively, users can launch Workbench directly from within a supported CAD system

Training Manual Introduction February 2, 2004 Inventory # … The ANSYS Workbench Start Page After launching ANSYS Workbench, the StartPage displays what options are available to the user: Launching the ANSYS Workbench StartPage does not use/require a license, although running Design Simulation does.

Training Manual Introduction February 2, 2004 Inventory # … The ANSYS Workbench Start Page The Workbench StartPage provides access to create, open, or import databases for a Workbench Project (next slide). Allows users to select a particular license Creates a new project in a given directory Opens an existing Workbench project Imports a stand-alone Design Simulation database (.dsdb) Imports a stand-alone DesignModeler database (.agdb) Imports a stand-alone DesignXplorer database (.dxdb)

Training Manual Introduction February 2, 2004 Inventory # … The ANSYS Workbench Start Page A new concept of Workbench Projects helps to organize dependencies between CAD or DesignModeler geometries, Design Simulation analyses, and DesignXplorer studies Workbench file (.wbdb) DesignModeler file (.agdb) Design Simulation file (.dsdb) DesignXplorer file (.dxdb) A Design Simulation database (.dsdb) can contain more than one analysis.

Training Manual Introduction February 2, 2004 Inventory # … The ANSYS Workbench Start Page Because of the new concept of Workbench projects, performing a simulation has changed slightly between 7.0 and 7.1/8.0. –In 7.0 and prior versions, the user would launch DesignSpace as a stand-alone application. A new ‘Geometry’ branch would be created, and the geometry from CAD or AGP would subsequently be attached. –In 7.1 and 8.0, a Workbench project is created to keep track of dependencies for the project. The geometry source is specified (from a file or active CAD/DM model), then, when a Design Simulation is chosen, the part/assembly is automatically attached, and a new Design Simulation is created. There is no longer any way to attach geometries from within Design Simulation. This must be done from the Workbench Projects page. There is no longer a “File > New” item in Design Simulation since a Workbench project must reference the geometry and associated simulation. “File > Save As…” has also been removed in the Design Simulation GUI. This action of “Save As…” can be performed from within the Workbench Project page.

Training Manual Introduction February 2, 2004 Inventory # … The ANSYS Workbench Start Page As noted earlier, the Workbench Project (.wbdb) keeps track of all associated files. Double-click on the DS icon to open the file from the Workbench Projects page.

Training Manual Introduction February 2, 2004 Inventory # … Launching Design Simulation If Design Simulation is launched from within the CAD software package directly: –The Workbench project filename and Design Simulation database will use the existing CAD part/assembly name. –The files will be saved in the working directory of the CAD files. –If files with the same name exist, a prompt will ask if you want to overwrite the files or not. If “yes” is selected, the noted files will be overwritten. If “no” is selected, the Workbench GUI will be displayed, and the user can specify another directory/filename to create the Workbench Project.
