NAME
       velvet - X11 based Finite ELemenT design and analysis

SYNOPSIS
       velvet [-toolkitoption] [-sensitive] [+sensitive] [-numbers] [+numbers]
       [-nodeColor color] [-elementColor color] [-toolColor color] [-labelFont
       font] [-toolFont font] [-nocpp] [-cpp filename] [-Dname[=value]]
       [-Uname] [-Idirectory] [filename]

DESCRIPTION
       Velvet is an X11 based finite element design and analysis package based
       on the felt(1fe) tool and the felt(4fe) input file syntax (velvet is
       smoother than felt).  If filename exists then it will be loaded upon
       startup.  Velvet attempts to locate a saved parameter file upon loading
       an input file.  A saved parameter file has a common prefix with
       filename but a ".vlv" extension.  If filename does not exist or is
       absent then velvet will start with an empty problem with the
       appropriate name.  Details of the mathematics and user interface can be
       found in the user's guide.

OPTIONS
       In addition to any standard toolkit option, velvet accepts the
       following options:

       -sensitive
            Enable sensitive/insensitive menu switching.  Velvet has two major
            modes of operation, normal mode and edit mode.  Each mode allows
            only certain operations to be performed.  This option allows
            disabling of the menus controlling the inactive operations.  This
            is the default behavior but may be inappropriate on a slow server.
            Associated resource: *sensitiveMenus.

       +sensitive
            Disable sensitive/insensitive menu switching.  Associated
            resource: *sensitiveMenus.

       -numbers
            Enable node and element numbering.  This is the default behavior.
            Associated resource: *numbers.

       +numbers
            Disable node and element numbering.  Associated resource:
            *numbers.

       -nodeColor color
            Sets the color of nodes and node numbers.  The default color is
            "blue".  Associated resource: *nodeColor.

       -elementColor color
            Sets the color of elements and element numbers.  The default color
            is "black".  Associated resource: *elementColor.

       -toolColor color
            Sets the color of tools (rectangles, lines, circles) and
            interactive windows.  The default color is "red".  Associated
            resource: *toolColor.

       -labelFont font
            Sets the font used for node and element numbers.  The default font
            is "5x8".  Associated resource: *labelFont.

       -toolFont font
            Sets the font used for text drawn using the tools.  The default
            font is "fg-22".  Associated resource: *toolFont.

       -nocpp
            Do not use a preprocessor on the input file.

       -cpp filename
            Use filename as a preprocessor on the input file.  The default
            preprocessor is "/lib/cpp".  Any preprocssor which understands the
            -D, -U, and -I options can be used as these options are passed to
            the preprocessor.

WIDGETS
       In order to specify resources, it is useful to know the hierarchy of
       the widgets which compose velvet.  The application defaults files
       contain (for the most part) fully qualified resource names and should
       be consulted if the resources are to be changed.
