      (continued)

       Many Femap preferences will take effect immediately after they
           have been set, but in some cases you will need to close and re-
           open Femap for the changes to take effect
              Examples of when Femap needs to be restarted to take
                  effect include:
                    Debug messages turned on for Render graphics
                    Performance Cache Pages and Blocks/Page have been changed
                    Fonts changed for the Messages Window, etc.

      Render

      Render mode is a high-speed
      graphics mode based on OpenGL
       Render dialog box controls the level
           of functionality while in Render
           mode
             Hardware Acceleration can be
                toggled off if the graphics card,
                or it's drivers are causing
                instability in Femap
             Including less entities with the
                Include In Dynamic Rotation
                option will speed up dynamic
                rotation of large models

      Graphics Card Performance
      Considerations

       Desktop area resolution should be taken into consideration when
            using Femap
       Having a very fine screen resolution can increase the time
            animations need to generate and the time individual windows need
            to refresh.
       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. (e.g. use an ATI or nVidia driver vs an ASUS
                driver)

                  user has placed a specific dialog
                  box on the screen (during the
                  current Femap session).

      Geometry/Model

      Select between the Standard or
          Parasolid geometry, Parasolid
          engine is recommended.
      The Solid Geometry Scale Factor
          is used to convert your model
          units into meters
             If you use inch units, there are
                 39.37 inches/meter and Femap
                 uses this number as scale factor to
                 store geometry in the model
                 database (1 inch = .0254 meters).

       The Alternate Section Property
           Calculator can be turned on in
           this dialog box. For this option
           Femap will use another method
           to calculate beam section
           properties which in certain cases
           will be more accurate than the
           standard method.
       The tetrahedral and surface
           meshing in FEMAP has changed
           in version 10. These two
           switches allow to always use the
           "pre-v10" tetrahedral and/or
           surface meshing from previous
           versions.

              Setting Solid Geometry Scale Factor
              e.g. 1000 indicates that the length
              units for this model are in mm




              The File, References command tracks the source file of the imported
                  geometry and will prompt the user to update a Femap model that has
                  it’s source geometry file modified when the Femap model is opened.
