Abstract
The method for reducing total computational time during iterative application of the force density method, intended to attain prescribed force values in cables or prescribed lengths of cable segments, is described in the paper. In each step of the iterative procedure, linear systems are solved with the accuracy that takes into account differences between the calculated and required values. The rule that prevents excessively fast increase in accuracy, while maintaining it high enough not to compromise the convergence of the iterative process, is proposed.
