The Fractal Nature of the Form Finding equations

For numerical experiments, a series of examples treating a cable net with a single free node with three degrees of freedom were performed. The convergence of the Newton-Raphson, modified Newton-Raphson, underrelaxation, line search and force density methods was analysed. The hypothesis that the basin of attraction is a fractal was confirmed.
