Although there have been many System Dynamics models written in DYNAMO, which are the common property in the society now, there are many obstacles recognized in studying these models using STELLA. This paper shows a conversion table of the basic DYNAMO rules into STELLA II in order to overcome these obstacles. First, we refer to the recent graduate increase of the papers System Dynamics Review, etc. which used STELLA I or STELLA II, and then we expect STELLA II for windows will be used more for model building in the future. Second, we refer to the general features of five differences between DYNAMO and STELLA II in terms of terminology, an equation, a time script, a time related character, and the relationship of Level and Rate (or stock and Flow), and then we refer to one similarity in terms of value chain. Third we show a comparison table of DYNAMO functions with STELLA II functions according to the categories of Delay and Smooth Functions, Logical Functions, Table Functions, and then we show a conversion table of DYNAMO functions into STELLA II functions using simple examples respectively. In addition, we show the applications of Sub-Model and Space Compression Object (SCO) of STELLA II functions, which are the new methods available in Stella II (Mac v3.0.4, 1993). In conclusion, we successfully convert the model of Saturday Evening Post written in DYNAMO (Hall 1973) into a model in STELLA II according to these our findings in order to estimate them.
