We use front tracking data structures and functions to model the dynamic evolution of the fabric surface which is represented by a surface mesh with preset equilibrium side lengths. The motion due to stretching and tension of the surface is solved by a system of ordinary equations for the spring model. We proved the existence of the upper bound of the eigen frequency for one of such systems and analyzed the numerical results of the superposition model. The spring model for fabric surface is coupled with the Navier Stokes equation through the "Impulse Method" for the simulation of parachute delivery system.  The numerical solutions are compared with the available experimental results.。
