In the Modeling Transient Flow section of the Simulation Settings menu, you will see fields for inputting the simulation start date and time (hour of the day), the simulation time-step, and the total simulation period. You can use theses text boxes next to ‘State Date’ (year, month, day), ‘Hr’ (hours), ‘Time Step:’ (days), and ‘Simulation Length’ (days) to define user inputs, but for this example we will use the default inputs (present day of access).
Note that the maximum number of time steps for the student version is 300. If you increase the simulation length, you will need to increase the time-step to ensure that your simulation reaches the end. If you decrease the simulation length, you can consider reducing the time-step to get more temporal resolution.
