Dear Temple!
you may want to take a look at Dynamic Applications. That's a free software that will allow you to create all kinds of simulation models. There are quite a few introductory products on our website, with basic examples of System Dynamics simulations. All simulations are self-explanatory with ToolTips showing formula and live values. The software is based on a differential equation solver, and so it is capable to adjust simulation models on-the-fly, with an Excel-style formula editor.
What you need to know is that the Target of this software is not complexity in math functions, but reduction, beauty, ergonomy and usability. So it's not super complicated for the scientists. We rather target mass adoption with introductory samples like 48-month business planners, so to make the idea of simulation modeling, balanced scorecards, and planning over time available to everyone. However, custom simulations models can be stored in a variant of XMILE, a common standard.
You can download any of our products and they are fully functional (try Startup Product Manager, and Photovoltaic System for a more complex example). The Pro version is called Perfect Desire, and it's business model is pay what you want.
For activating the formula system, you'll need the following Promo Code: DLROW-III-MODEL
A water chain simulation is in our dynamic idea voting competition, but it's not yet on the Top. We're working from Top and we publish all favourite simulations of our fan crowd for free.

Our rates start from 25 €/h for Startups, platform development is 33 €/h, customizations 66 €/h. Introductory support is free.
Let me know if you got questions.
Best Regards,
