ADAMS/VIEW INTERFACE OVERVIEW SECTION 3 ADAMS/VIEW INTERFACE OVERVIEW

What is in this Section Model Hierarchy Renaming Objects Adams/View Interface Simple Simulations Saving Your Work

Model Hierarchy Adams/View Modeling Hierarchy Adams/View names objects based on this model hierarchy. For example, Adams/View names geometry as .model_name.part_name.geometry_name. To change the parent for an object, rename the object. Model Analyses Measures Forces Constraints Parts Results Sets Components Markers Construction Points Geometry Simulations Objects More Are not saved in model command files (.cmd) Draw figure on board. Demonstrate: In the stamping mechanism, display the names of parts to illustrate the model hierarchy. Right-click the parcel’s part. Show how it is made up of several geometries. While right-clicking, reiterate that in Adams/View, left-clicking selects objects while right-clicking displays a menu. See Also: Assembling Subsystem Models in Section 14

Renaming Objects Adams/View naming conventions: .mod .mod.run_1 .mod.meas_1 .mod.spring_1 .mod.joint_1 .mod.part_1 .mod.run_1.joint_1 .mod.run_1.joint_1.fx .mod.part_1.mar_1 .mod.part_1.point_1 .mod.part_1.box_1 Simulations Objects More Are not saved in model command files (.cmd)

Renaming Objects (Cont.) Renaming objects clarifies model topology Names can have underscores but not spaces or symbols Zoom in on bottom half of the page and stress the importance of renaming parts, joints, and so on. Stress that giving descriptive names to objects makes debugging much easier. Not renamed Renamed

Simple Simulations Simulation versus animation Simulations are solutions to equations of motion describing a mechanical system. Animations display a graphical playback of previously completed simulations. Simulation output Step Size: amount of time between steps Steps: total number of steps in a specified amount of time Simulation time interval End Time: absolute point in time to stop simulation Duration: relative amount of time to simulate over Explain that the simulation time interval option of Forever is available from the Simulate menu, not from the toolbox. Create a simple pendulum and demonstrate all the items called out in the figure above. Demonstrate the Main Toolbox: Tool stacks - Accessed by right-clicking a tool. Container - Appears in the bottom half of the toolbox when a tool is selected. Demonstrate the Status bar: Ask them to look at the Status bar for directions from Adams. Explain that the view triad provides a visual reference; it is not an object and cannot be selected. Simulate the pendulum and then animate it for a graphical playback. Explain how the time interval and the output options work. Animation tool

Saving Your Work Most common formats in which you can save Adams/View models Adams/View database files (.bin) Include the entire modeling session including models, simulation results, plots, and so on. Are typically large (start at 5 MB). Have been platform independent since Adams 11.0 (2002) Adams/View command files (.cmd) Include only model elements and their attributes. Are relatively small, editable text files. Are platform independent. Demonstrate Export Versus Save Database: Use the pendulum you created earlier. Once both .cmd and .bin files are created, illustrate the difference in the size of the two files. Open the .cmd file in a text editor to show how simple it is but do not get into details about the commands.

Saving Your Work (Cont.) Other formats in which you can import and export data Adams/Solver input files (.adm) Geometry files (STEP, IGES, DXF, DWG, Wavefront, Stereolithography) Test and spreadsheet data files Simulation results files (.msg, .req, .out, .gra, .res). The other formats will be discussed in greater detail later in the course.

Adams/View Graphics on Windows Adams/View uses the OpenGL graphics standard Early versions of Windows graphics card drivers sometimes do not have OpenGL fully implemented Signs of graphics driver issues: Display “freezes” (stops updating) Adams/View application crashes or disappears Adams Exception 11 errors SOLUTION: Update the graphics card drivers http://www.nvidia.com then pick Download Drivers For ATI and AMD video cards, http://support.amd.com The other formats will be discussed in greater detail later in the course.
