Duration of simulation

It is recommended to take into account both the spin up time and the duration of the time series at the wavemaker boundary.
In this way, a steady-state condition will be obtained. We assume that the spin up time takes at most 10 to 15% of the total
time of the simulation. For a suitable simulation time at least 500 to 1000 waves are needed.

In the above example the cycle period equals 30 minutes, which is supposed to be at least 85% of the total simulation time.
So, the duration of the intended simulation would be 35 minutes, or more safely, 40 minutes.
