For these reasons it is necessary to find a numerical model of simulation which obviously replaces the experimental process to give reliable results with cheaper conditions in terms of cost and time which has been respected which allowed us to collect data. Results and compare the different heights calculated and measure and often confirm the experimental tests.en
