| <h1>STEM Quick Start</h1> |
| <p>When you first start STEM it will display the <a href="../interface/perspectives/simulation.html">Simulation |
| perspective</a> containing a <a href="../interface/views/scenariosview.html">Scenarios view</a>. This |
| view contains a hierarchical display of the <a |
| href="../concepts/modelingframework.html#scenario"> Scenarios</a> that |
| are built in to STEM and are ready to start a Simulation. See |
| Figures 1 and 2 below. |

| <p>Figure 1. |
| <p>Expand the tree displayed in the <a |
| href="../interface/views/scenariosview.html">Scenarios view</a> to |
| display the available <a |
| href="../concepts/modelingframework.html#scenario"> Scenarios</a>. |
| Select one of the displayed <a |
| href="../concepts/modelingframework.html#scenario"> Scenarios</a> by |
| "double-clicking" on its title, Figure 2. </p> |

| <p>STEM will immediately begin reading in |
| the data that defines the Simulation. It's progress is displayed at the |
| bottom of the window. The amount of time it takes to read in the data |
| for the Simulation will depend upon the size of the model and the |
| characteristics of the host computer. On a fast computer with more than |
| 2 gigabytes of RAM and fast disks the <a |
| href="../concepts/modelingframework.html#scenario"> Scenario</a> |
| illustrated in Figure 3, below, will load and began execution in |
| less than 5 seconds. On a smaller slower machine (e.g., a small laptop |
| with slow disks), this could take 30 seconds or longer).</p> |

| <p>Figure 3 |
| <p>In Figure 3, we see the state of the simulation after about 55 iterations. In this case, |
| the disease is spreading across common borders from starting in the north |
| and moving south. |
| <p> |
| The "Simulation control" area in the lower left is used to "Start", "Pause", "Reset", |
| "Step" and "Stop" all the active Simulations. |
