Abstract

A recording-medium-type setting unit selects a type of a recording medium to be analyzed on the basis of information input with an input unit. A threshold-value setting unit sets a threshold value on which the determination of whether the calculation result is output in a file is based for each recording medium type selected by the recording-medium-type setting unit. An amount-of-variation calculating unit calculates the reaction force for every time step, stores the reaction force in the current time step in time integration in a RAM during the calculation, and monitors the amount of variation in the reaction force between each time step and the next time step. A file-output controlling unit calculates the difference between the reaction force stored by the amount-of-variation calculating unit and the reaction force in the current time step and, if the difference is larger than the threshold value, performs file output.
