ABSTRACT:
In a calculating apparatus for calculating a predictive shape of a wire structure using a finite element model, a predictive shape of the finite element model which is in a physically balanced condition based on physical properties and restriction conditions is calculated. When it is determined that the predictive shape of the finite element model crosses an obstacle model, the control point of the finite element model is returned to a position corresponding to a position immediately before the crossing of the joint with the obstacle model and a crossing joint which is the joint crossing with the obstacle model is bound to a contact point of the finite element model with the obstacle model. The predictive shape is output when the control point is returned to a position at the time of crossing of the finite element model with the obstacle while maintaining the binding.
