Vensim Help

In addition to building models, you can use the build window to perform simulation tasks.  Most importantly, you can enter Simulation Setup mode and SyntheSim mode from the build window.  In Simulation Setup mode all model Constants and Lookups will be highlighted.  By clicking on them you can make temporary changes to the values to be used for a simulation.  In SyntheSim mode each model Constant will have a slider attached that you can use to adjust values.   You enter Simulation Setup and SyntheSim mode by clicking on the associated icon in the Toolbar.
