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.


Grain Size Specification

Card Arguments Example Description
SEDIMENT_SIZE_CLASS_NUMBER INTEGER 3 Specifies the number of grain size classes.
MULTIPLE_GRAIN_SIZES INTEGER [REAL, REAL,..., REAL] 3 0.1 0.2 0.3 Specifies the number of grain sizes followed by the grain sizes for each size class in mm.
SEDIMENT_SIZE_CLASS_DIAMETERS INTEGER [REAL, REAL,..., REAL] 3 0.1 0.2 0.3 Specifies the number of grain sizes followed by the grain sizes for each size class in mm. Same as ULTIPLE_GRAIN_SIZES.
SEDIMENT_SIZE_CLASS_LIMITS INTEGER [REAL, REAL,..., REAL] 4 0.07 0.15 0.26 0.34 Specifies the size classes limits. The first entry is the number of size class limits which is one greater than the number of size classes.
