Abstract:
1. A method of calculating a predictive shape of a wire structure, comprising of: providing a finite element model of the wire structure, the finite element model being formed as an elastic body having a plurality of linearity beam elements combined at respective joints; setting physical properties and restriction conditions of the wire structure to the finite element model; calculating a predictive shape of the finite element model which is in a physically balanced condition based on the physical properties and the restriction conditions; determining whether the predictive shape of the finite element model crosses an obstacle model representing an obstacle when a control point of the wire structure is displaced; returning the control point of the finite element model to a position corresponding to a position immediately before the crossing of the joint with the obstacle model, and binding a crossing joint which is the joint crossing with the obstacle model, to a contact point of the finite element model with the obstacle model, when it is determined that the predictive shape crosses the obstacle model; and outputting the predictive shape at the time when the control point is returned to a position of the crossing while maintaining the binding.
