Claim 4:
5. The method of claim 1, further comprising:
generating, by a deep learning model generation unit including the at least one processor, the deep learning model,
wherein the generating of the deep learning model includes:
generating, by a learning data generation unit of the deep learning model generation unit, learning data having a rough contact surface of a fractal structure by calculating random midpoint displacement; and
learning, by a deep learning model learning unit of the deep learning model generation unit, the deep learning model using the learning data, and

wherein the calculating of the random midpoint displacement is a scheme of adding a random value generated according to the Gaussian normal distribution to an average of heights corresponding to grid points of the learning data to randomly calculate a height of a new grid point surrounded by the grid points.
