In this research, we are investigating the simple calculation method using FEM software. The simplified calculation method obtained a result that was almost the same between the standard and the value to be predicted. If an accurate calculation result is obtained, it is necessary to use a conventional calculation method. It was confirmed that the calculation of NLCM was established using the function of FEM. It was confirmed that NLCM is established even if the element division of FEM is finely divided. It was confirmed that the auto step function of FEM had no effect.
