STELLA – Overview TELI-G | Tufts University | 1-17-2015 Stocks flows connectors LinksSector frames Graph table Erase Copy View the math behind the model Edit the values in stocks and flows Visualize the system in this tab (start here) Interact with the simulation – add buttons, etc

STELLA – Goals for Today TELI-G | Tufts University | 1-17-2015 Today, we’re making a mass flow (m 3 ) diagram for ceramic filters (an example) General thoughts: System boundaries? Functional unit? Flows and stocks? End output? Life cycle/time boundaries? You can apply these to your own work as well!

STELLA – Goals for Today TELI-G | Tufts University | 1-17-2015 We’ll go through a simple system and see the outputs given While I do this – think about how you could apply this to your work Feel free to ask questions, now and during the practice period

STELLA – Resources TELI-G | Tufts University | 1-17-2015 iSee systems Tutorials – great for specifics on what buttons do: http://www.iseesystems.com/community/downloads/tutorials/ModelB uilding.aspx http://www.iseesystems.com/community/downloads/tutorials/ModelB uilding.aspx Carleton College - good for general model ideas: http://serc.carleton.edu/introgeo/mathstatmodels/StellaHow.html http://serc.carleton.edu/introgeo/mathstatmodels/StellaHow.html Getting Started With STELLA (ThoughtMap) - good high level overview: http://www.thoughtmap.com/storage/files/Getting%20Started%20with%20iThink %20and%20STELLA.pdf http://www.thoughtmap.com/storage/files/Getting%20Started%20with%20iThink %20and%20STELLA.pdf

STELLA – Resources TELI-G | Tufts University | 1-17-2015 Also will email out all of the STELLA files I’ve used – from chemical equilibrium of phosphorus in lakes to population growth dynamics You can use these as examples Also.stm files are sometimes added to papers (see citations)
