Figure 1. CMS-Flow Model Control : Model Parameters tab in SMS 11.0.

All of the CMS-Flow model parameters, settings, and output options are controlled from the CMS-Flow Model Control window (Figure 1). The window has several tabs including the Flow tab in which most of the general settings are set for CMS-Flow. To open the CMS-Flow Model Control window, click on CMS-Flow | Model Control. The first tab will be the Flow tab. There are several sections within the tab including Time Control and Hot Start options.

Time Control

Below are some of the CMS cards related to the Time Control of the Flow tab. Table 1 provides a brief description of the CMS cards used for time control.

DURATION_RUN REAL 48.0 >RAMP>0 Sets the duration of the model simulation in hours.
DURATION_RAMP REAL 1.0 Sets the length of the ramp period in which the model forcing is slowly ramped from zero.

Hot Start
