CASIM program

You may have occasion in a report or publication, to refer to the CASim program. The program should be identified as follows ... 

Run a model of water using the parameters shown in Example 3.1 in the Program CASim. 

In this study the concentration of the water in the grid is adjusted to correspond to the density (specific gravity) of water at various temperatures. These adjusted concentrations are shown in Table 3.1. Run the example 3.2 for the adjusted concentrations of water in Example 3.2 in the program CASim for a temperature of 20°C. 

This example uses the variegated cell pattern aabb shown in Figure 3.6. Use Example 3.3 in the program CASim. Results from this example are compared... 

Water molecules are placed in the lower half of the grid, leaving the upper half empty. A temperature is selected using the Fb and J parameters and the CA is allowed to run for a specified time. The number of water molecules in each row of the upper half of the grid is counted. The grid is defined as a cylinder with the upper and lower boundaries stationary. This prevents water movement past the bottom boundary. A profile of evaporation versus temperature can be obtained by varying the simulated temperature. Use Example 3.5 in the Program CASim. 

This example describes two liquids, X and Y, with parameters that describe their aversion to each other. This is accomplished with Tb(XY) = 0.5 and J(XY) = 0.7. The gravity terms are created to impart a preference for one ingredient to move lower in the grid than the other ingredient. In this example setup, the Y is slightly favored to move lower than the X ingredients. Use Example 5.1 in the program CASim to run this example. 

This software is written in Java programming language. To run this Java application, the J2SE (v 1.4.2 or higher version) Java runtime environment must be installed. There is a free download web site http //iava.sun.eom/i2se/l.4.2/ download.html. The CASim software is designed to run on any computer that supports Java 1.4.2 or later Java runtime environment. (This includes almost all Windows, Macintosh, and linux systems.)...
