  COMMAND PWAVE3DFRAME
-----------------------------------------------------------------
    Purpose: 3D-particle-wave (along x-,y- and z-axis), single object
      Usage: PWAVE3DFRAME(<particleID>,<frames>,<frame>,<destID>,<"S" or "F">,
                          [<amplitude>,<wavelength>,<sourceX>,<sourceY>,
                           <sourceZ>,<damping>,<phase in degrees>])
   Examples: pwave3dframeframe(1,40,24,2,f,14.0,32.0,10,-10,12,1.2,-30.0)
             pwave3dframe(1,60,33,4,s)
