I recently realised that the results of the simulations vary depending on the simulation time. Since this happens, I started wondering if there’s a recommended TTI so that the results are more according to reality. When it comes to the 3D model, I saw that the TTI by default is 20, so, is that the recommended simulation time? Thank you for your time and attention.
the total length of your simulation depends on what scenarios you actually want to simulate and the metric that you consider in the end. A good way for you to test if you are averaging over enough TTIs, is to check the size of the confidence intervals of your average values.
Since the 3D model is quite complex computationally, simulations with large numbers of TTIs take a lot of time – therefore you might really consider to simulate just as many TTIs as needed to get statistically meaningful results.
