A golf ball trajectory simulation method is provided. The method includes setting up a golf ball model within a virtual airflow space where a grid has been generated and setting a weight for the ball model and applies initial conditions (initial velocity, launch angle, spin rate) to the ball model so as to cause the model to fly within the virtual airflow space. The method further includes calculating the lift coefficient and the drag coefficient for the golf ball from the air stream velocity, the direction and pressure in each grid cell, and the flight distance and left-to-right dispersion for the golf ball from launch until landing by calculating, at predetermined short time intervals, the change in height, change in lateral direction, change in velocity and change in spin rate for the golf ball during flight.
