Berkeley Madonna Tutorial 2

3.4 System Dynamics Tool: Berkeley Madonna Tutorial 2 Introduction to Computational Science: Modeling and Simulation for the Sciences Angela B. Shiflet and George W. Shiflet Wofford College © 2006 by Princeton University Press Prerequisite: "Berkeley Madonna Tutorial 1" Download Download from the text's website the file unconstrained, which contains a Berkeley Madonna model to accompany this tutorial. Introduction This tutorial introduces the following functions and concepts, which subsequent modules employ: Built-in functions and constants, such as IF, THEN, ELSE, ABS, INIT, EXP, TIME, PI, PULSE, DT, SIN, and COS; relational and logical operators; comparative graphs; and graphical input. Optionally, we cover conveyors, which are useful for some of the later projects. To understand the material of this tutorial sufficiently, we recommend that you do everything that is requested. While working through the tutorial, answer Quick Review Questions in a separate document. Built-ins We can enter equations into a reservoir, flow, or formula of a Berkeley Madonna model. Equation Help under the Help menu summarizes Berkeley Madonna's functions and features. In this tutorial, we consider several of these functions that enable us to effectively model many more situations. Table 3.4.1 lists many of the Berkeley Madonna functions along with their formats and meanings. The following tutorial illustrates a number of these through examples. ...
