The Output Level allows the user to control how much logging information is written to the Computation Log File as well as select a predefined list of output variables. The Output Level is set within the Sediment Output Options editor which is accessed by clicking on the Options | Sediment Output Options menu within the Unsteady Flow Analysis editor (see figure below).
