As a concusion, in the a comparison of the results obtained in this case (labeled as Tdyn S&T), the results of the previous example (labeled as Tdyn) and the results of the experiments are shown. As can be seen, the accuracy of the results has been increased, due to the mesh updating, based on the previous results.

The resulting forces data can also be compared with the resistance values of the free to sink and trim model experiments.
The new result of the viscous coefficient of our calculation is very similar to the obtained in the previous example Cv = 2.90·10-3, while the pressure force obtained in this simulation is Cw = 1.95·10-3. These values gives a total resistance coefficient of CT = 4.85·10-3, very similar to the experimental data found.
