CMS-Flow Model Parameters
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.
The general parameters are the water density and temperature. The CMS-Flow cards for the general parameters are described in the table below.
Table 1. CMS-Flow cards related to the general parameters
|WATER_DENSITY||REAL||1025||Water density in kg/m^3.|
|WATER_TEMPERATURE||REAL||15||Water temperature in degrees Celcius.|
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.
|STARTING_JDATE||REAL||none||none||Julian data in YYDDD with YY being last two digits of the year, and DDD the Julian day of the year.|
|STARTING_JDATE_HOUR||REAL||none||none||Julian hour .|
|HYDRO_TIME_STEP||REAL||Calculated based on solution scheme and courant number||none||Sets to the time step for hydrodynamics in seconds.|
|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.|
