After install of FEMAP, the Sentinel System Driver (used to access the security device) will be installed. Complete will install both of the parallel and USB security device drivers. Custom will let you select between parallel and USB Slide 8 8 Updating a Previous Installation Auto run on NT4.0, 95, 98, and 2000 Administrator Privileges Required for NT and 2000. Modify displays a list of FEMAP components with the installed components checked. Check components to add them, and uncheck to remove them. Repair will automatically reinstall into the existing previous installation, replacing the corrupted installation. Remove will completely remove FEMAP from the system. Slide 9 9 Graphics Considerations A very high windows color resolution is not needed with CAD and FEA programs, and might actually cause slower graphics performance. 16 Million colors is a recommended setting, or 8 bit True Color. The desktop area resolution must also be taken into consideration. Right mouse button on Windows Desktop Select Properties, then Settings Adjust Color Palette and Desktop Area to optimum for your graphics card Use Test to verify support by your graphics card of combination of Palette and Area Graphics appearance relies on your Windows Settings (more is better) If FEMAP appears to be having graphics errors, it could be the driver for your graphics card. Update the drivers for your graphics card often! Drivers from the manufacturers of the graphics card chipset tend to be more stable then the drivers from the maker of the graphics card. Slide 10 10 FEMAP Preferences Configure FEMAP for optimum performance and the way you prefer to work. Divided into two categories, User Interface, and Program Options File Preferences. Be sure to exit FEMAP and start it again for the new preferences to be applied. Slide 11 11 Program Options - Database and Startup Select File - Preferences, choose Database Define various Database Memory settings Cache Pages, Blocks/Page and Max Cached Label for improved RAM management and performance. More information on page 3-17 of the User Guide. Specify Scratch Disks for the location of the temp, scratch, and recovery files FEMAP writes out. The Windows temp directory is the default. The Windows temp directory is an environment variable in Windows that can be modified by right clicking on My Computer, and selecting properties. Installed RAMCache PagesBlocks/Page 12880002 256120003 512150005 10001500011 Slide 12 12 Program Options - Geometry Select File - Preferences, choose Geometry Can select between the Parasolid, Acis, and Standard geometry engines to start with. The Parasolid engine is recommended. The scaling of geometry is done internally in FEMAP so that a part of 1.0 on the desktop will be stored as 0.0254 in the database. This scaling will allow you to import and model parts that are outside of the Parasolid modeling limits (500x500x500). If you import geometry with a different scale then the internal scale, new or modified geometry will be out of scale with the imported geometry. Load Expansion on Midside Nodes sets the defaults for modification of the distribution of nodal loads (such as force and moment) on parabolic elements. To obtain an even distribution of force across a parabolic element, most programs require a larger portion of the force be assigned to the midside nodes. You can set the factors Along Edges, On Tri-Face, or On Quad-Face to represent the amount of the total load on the element which will be applied to the midside node. You will typically want to use the default values above, as well as use the Midside Node Adjustment Default. If you have further questions on the distribution required for your solver program, please consult the reference documentation for your analysis program. Slide 13 13 Program Options - Interfaces, Libraries and Colors Interfaces preferences control the FEMAP defaults for creating analysis models. The defaults can be defined for each interface (eg NASTRAN, ABAQUS, etc.) The Libraries preferences allow you to select the default libraries the FEMAP uses. The Colors preferences allow you to select the default colors for entities. Slide 14 14 User Interface - Messages and Lists, View and Graphics. Messages and Lists Preferences control text displayed in the Messages and Lists window and the size of that window. When you select the Messages and Lists Window option, you will see the Preferences dialog box. These options are partitioned into two major types: Borders and Size, and Fonts and Colors. In Views and Graphics Preferences, the startup view allows you to specify a view other then the default startup view so that you dont have to re-specify view options. Views are saved in View Quick Options (Ctrl Q). If you see flicker during Dynamic Rotation, try customizing the options for View and Dynamic Rotation. Slide 15 15 User Interface Render Graphics Render mode is a high-speed graphics mode that uses the OpenGL graphics language. The Render Graphics Preferences dialog box lets you control the Render graphics method used, as well as the level of functionality that you have while in Render mode You can choose between two Render methods: Original or Enhanced. Generally, you should use the Enhanced method. The Enhanced method doesn't support a few post-processing displays. For these types of displays, you must set the method to Original: beam diagrams isosurfaces section cuts vectors (contour and deformed), deformed trace plots freebody displays Hardware Acceleration can be toggled off if the graphics card, or it's drivers, are causing instability in FEMAP. Slide 16 16 User Interface Menus and Toolbars, User Menus, Shortcut Keys Change the Menus and Toolbar preferences to suite your working style The User Menus preferences allow you to integrate custom API scripting and program files into FEMAP. This will be touched upon further in the API section of the training manual. Shortcut keys are assigned so that any command in FEMAP can be accessed by pressing a key. Good for commonly used commands.

Access to all commands through drop-down windows. Lists Short-Cut Keys on menu. Provides quick access to commands via Toolbars. View Toolbar Command Toolbars Slide 21 21 Toolbars View Toolbar - typically above Graphics Window Provides access to view commands while in other dialog boxes. Important for positioning of model while picking entities. Command Toolbars - Typically right of graphics Window Provides shortcut to commonly used commands. Multiple levels of Toolbars for access to large number of commands. Very convenient when creating geometry and post- processing results. Slide 22 22 Status Bar and Tray Contained at bottom of FEMAP Main Window Provides running total of nodes and elements in model. Short description of commands when in the menu structure of FEMAP. Tray on Right Provides Access to Current Entities Property, Load Set, Constraint Set, Group, Output Set Change Current Entity or create a new one Dynamic Query - end of Tray Select Type of Entity (Defaults to OFF) Hold Cursor at an entity on the screen Information about entity provided in Tooltips Box Slide 23 23 Graphics Windows Multiple Windows available.
