1. [math]\displaystyle{ t_1 \gt \Delta t \, }[/math] (outer time step)

   In the considered time interval, no section change takes place .

2. [math]\displaystyle{ 0 \lt t_1 \lt \Delta t \, }[/math]

   After the time t1, there is a section change . The span between t0 and t1 represents the length of the inner time step.

3. [math]\displaystyle{ t_1 \lt 0 \, }[/math]

   There is no storage content increase but a decrease. Instead of the upper section boundary, the lower section boundary must be used and the calculation repeated.
