21、ser interface environment that emphasizes access to commands,customization and scripting.Formerly called the ANSYS PREP7/POST1 interface,Product Configuration,Types of licenses available for Mechanical:Various ANSYS licensing configurations are available.The license chosen will dictate what features
22、 and capabilities are available in the Mechanical application.License management allows license sharing when multiple instances of a particular application are open.(Other ANSYS licenses are supported for meshing only),Product Configuration,Add-on licenses for Mechanical:Rigid and Flexible Dynamics(
23、one add-on license)Fatigue Module12.0 Workbench products are available for Windows and Linux operating systems.Note,Linux will be supported starting at the 12.1 ReleaseCheck the ANSYS web site or online documentation for the latest compatibilities.Network licensing capabilities are used for all ANSY
24、S and ANSYS Workbench products.,D.Starting Mechanical,There are two methods of launching Workbench:From the Windows start menu:From the CAD system,E.The Workbench Environment,For most situations the Workbench GUI is divided into 2 primary sections(there are other optional sections well see in a mome
25、nt):,The Toolbox,The toolbox contains 4 subgroups:Analysis systems:predefined templates that can be placed in the schematic.Component systems:various applications that can be accessed to build,or expand,analysis systems.Custom Systems:predefined analysis systems for coupled applications(FSI,thermal-
26、stress,etc.).Users can also create their own predefined systems.Design Exploration:Parametric management and optimization tools.,.The Toolbox,The systems and components displayed in the toolbox will depend on the installed products.Using the check boxes in the“View All/Customize”window,the items dis
27、played in the toolbox can be toggled on or off.The toolbox customization window is normally left closed when not in use.,The Project Schematic,The Workbench project schematic is a graphical representation of the workflow defining a system or group of systems.The workflow in the project schematic is
28、always left to right.There are currently several applications which are native to Workbench,meaning they run entirely in the Workbench window:Project Schematic,Engineering Data and Design ExplorationNon-native applications(called data-integrated)run in their own window:Mechanical(formerly Simulation
29、),Mechanical APDL(formerly ANSYS),ANSYS Fluent,ANSYS CFX,Etc.Blocks of cells can be deleted by RMB on the block header cell that is shaded in blue.,.The Project Schematic,In this example a Static Structural analysis type is selected for the project schematic.From the toolbox the selection can be dra
30、gged and dropped onto the schematic or simply double clicked.,.The Project Schematic,By dropping applications and/or systems into various locations in the schematic,an overall analysis project is defined.“Connectors”indicate the level of collaboration between systems.In the example below a structura
31、l system is dragged and dropped onto a thermal system at the Model cell(A4).Before completing the operation notice there are a number of optional“drop targets”that will provide various types of linkage between systems(continued next page).,.The Project Schematic,By completing the operation from the
32、previous page,notice the linkage here is only at the Model level and above.In this case there would be no thermal/structural coupling.Notice too each system block is given and alphabetic designation(A,B,C,etc.).,.The Project Schematic,By dropping the structural system at the“Solution”level we obtain
33、 a structural system that is coupled to the thermal solution.,Notice,the candidate“drop target”indicates data will be shared from fields A2 to A4,and transferred from A6.,.The Project Schematic,A schematic can also be constructed by RMB and choosing to“Transfer Data To New”or“Transfer Data From New”
34、.In using this RMB transfer feature all transfer possibilities(upstream and downstream)are displayed.These selections will vary depending on which cell in a particular system you highlight.,.The Project Schematic,Identifying cell states:Unfulfilled:missing upstream data.Attention required:may need t
35、o correct this or upstream cells.Refresh required:upstream data has changed.Need to refresh cell(update will also refresh the cell).Update required:the data has changed and the output of the cell must be regenerated.Up to date.Input changes pending:cell is locally up to date but may change when the
36、next update is performed due to upstream changes.,Optional Workbench Windows,The“View”menu(and RMB)allows additional information to be displayed in the Workbench environment.Below,the geometry is highlighted and the properties are displayed.,F.Workbench File Management,Workbench creates a project fi
37、le and a series of subdirectories to manage all associated files.Users should allow Workbench to manage the content of these directories.Please do NOT manually modify the content or structure of the project directories.When a project is saved a project file is created(.wbpj),using the user specified
38、 file name(e.g.MyFile.wbpj).A project directory will be created using the project name.In the above example the directory would be MyFile_files.A number of subdirectories will be created in the project directory(explained next).,.Workbench File Management,Directory Structure:dpn:this is the design p
39、oint directory.This essentially is the state of all parameters for a particular analysis.In the case of a single analysis there will be only one“dp0”directory.global:contains subdirectories for each application in the analysis.In the example at right the“Mech”directory will contain the database,and
40、other associated files from the Mechanical application.SYS:the“SYS”directory will contain subdirectories for each system type in the project(e.g.Mechanical,Fluent,CFX,etc.).Each system subdirectory contains solver specific files.For example the MECH subdirectory would contain the results file,the ds
41、.dat file,solve.out file and so on.user_files:contains input files,user macro files etc.that may be associated with a project.,.Workbench File Management,From the Workbench“View”menu activate the“Files”option to display a window containing file details and locations.,.Workbench File Management,Archi
42、ve:quickly generates a single compressed file containing all pertinent files.File is zip format and can be opened using the“Restore Archive.”utility in WB2 or any unzip program.Several options are available when archiving systems as shown here.,G.Working With Units,The Units menu in Workbench:Allows
43、 access to predefined unit systems.Allows the creation of custom unit systems.Controls unit display for Engineering Data,Parameters and Charts.Activate the Units System dialog to control.,.Working With Units,Create custom unit systems by duplicating existing systems then modifying.Custom unit system
44、s can be exported and imported.,H.License Preferences,Workbench license control is handled through the user interface shown below,activated from the Workbench project page(“Tools License Preferences.“).,.License Preferences,With the available licenses displayed,the activation and“use order”can be sp
45、ecified using the up/down arrows.0=off,1=onLicense order represents the preference order for license use.,The license control allows Workbench users to specify whether a single license is used when multiple applications are open,or if all open applications access their own license.,.License Preferences,In the example shown,a user could have 3 Mechanical models open simultaneously.Using the license control they may choose to open 3 licenses or use only 1 that is shared.In the shared scenario,only the active Mechanical session uses the license(the remaining will be read only).,
