       Felt is a command line based finite element engine which reads a
       felt(4fe) file and writes the results to standard output.  If no
       filename is given then the standard input is used.  Any syntactic or
       semantic errors are reported to standard error.  A complete description
       of the mathematics can be found in the user's guide.

       Felt accepts the following options:

            Write the current version number and exit.

            Write a message describing valid command line options to standard
            error and exit.

            Write the processed file to standard output in the form of a valid
            input file.

            Write an ASCII rendering of the problem geometry.

            Write a material summary describing the total length, area, and
            volume of each material used to standard output.

            Include a time-displacement plot in the output of a transient
            analysis problem.

            Do not output a table of times vs. displacements in the output of
            a transient analysis problem.  Simple tabular output is the

            Only compute transfer functions for spectral analysis (stop
            calculations before output spectra are computed).

            Only perform the eigenvalue calculations (natural frequencies and
            mode shapes) in modal analysis.

            Use orthonormal mode shapes when calculating modal matrices
            (normalize the eigenvectors such that the modal mass matrix is the
            identity matrix).

            Make an attempt at optimally renumbering the nodes in order to
            minimize the storage requirements of the stiffness (and mass and
            damping) matrices.  This option will invoke a GPS/Gibbs-King
            renumbering algorithm.  For small problems the extra overhead of
            this algorithm is probably not worth the effort.  For large
            problems (> 100 nodes or so) the savings in both memory and
            overall execution time can be quite significant however.

            Print the global (stiffness, mass, damping) matrices that are
            appropriate to the analysis type for this problem.

       -graphics filename
            Create filename as a graphics file in gnuplot(1) format for
            visualizing the structure.  This option is used by xfelt(1fe).

            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.

       Felt was developed by Jason I. Gobat (jgobat@mit.edu) and Darren C.
       Atkinson (atkinson@ucsd.edu).
