Example: Flutter Analysis of a Swept Wing
-----------------------------------------

Model definition:

  parameters.m       defines all parameters
  make_constants.m   updates file constants.geo using parameters.m
  constants.geo      contains the geometric parameters for gmsh
                     (included by file solid.geo)

  modes.m            defines the solid model and computes normal modes
  aero.m             defines the aerodynamic model
  aeroelastic.m      defines the aeroelastic model

Flutter analysis:

  flutter_k1.m       1st flutter analysis using the k-method
  flutter_k2.m       2nd flutter analysis using the k-method
  flutter_pk.m       flutter analysis using the pk-method

Post-processing:

  plot_k1.m          Flutter curves to flutter_k1
  plot_k2.m          Flutter curves to flutter_k2
  shape_k2           Flutter mode shape to flutter_k2
  post_pk            Flutter curves and flutter mode shape to flutter_pk

Binary files:

  modes.m       => solid.bin        => aeroelastic.m
  aero.m        => aero.bin         => aeroelastic.m
  aeroelastic.m => aeroelastic.bin  => flutter_k1.m
                                    => flutter_k2.m
                                    => flutter_pk.m
  flutter_k1.m  => flutter_k1.bin   => plot_k1.m
  flutter_k2.m  => flutter_k2.bin   => plot_k2.m
                                    => shape_k2.m
  flutter_pk.m  => flutter_pk.bin   => post_pk.m
