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.
