Zoom In Zoom Out Show View1 Show View2 Show View3 Show View4 Module Name 5.1.3 Build a program Figure 5-4 Instruction of Module Interface The previous section shows how to create a module in the sequence view. A simulation application can be built by creating a sequence of modules. Figure 5-5 shows an example of “Hybrid simulation” built in the sequence model. In this example three kinds of molecules are created: “water”, “oil” and “surfactant”. Among these molecules, “oil” molecules are concentrated in a sphere. (It is a drop of oil). The red area in Figure 5-5(b) refers to this oil droplet. “Water” molecules are distributing in the other area out of the oil drop. And then 100 surfactant molecules are added to this environment (see the white and blue molecules in Figure 5-5(b)). Then the properties of each kind of molecule and the relationships among these molecules are specified. The properties about this environment such as the temperature are set as well. At the end, the parameter simulationstep is set. Figure 5-5(a) shows a part of this application. Clicking the “run” item in the menu, the program will be executed. Figure 5-5(b) shows the initial state of the simulation. Figure 5-5(c) is a visual display generated during of the simulation. And Figure 5-5(d) is the end result of the simulation. As can be seen from these images, the surfactants first distribute randomly in the whole area. Then they move to the oil gradually, and finally all of them surround the oil droplet. In the concept model, the creation of an instance of a module is almost the same as in the sequence model. The only difference is that only some kinds of modules are allowed to a certain area. For example, if the space is used to place the modules from SetViewer, the modules which are not belong to this category like DPDCalculator cannot be put in this space. Figure 5-6 and Figure 5-7 show a DPD simulation program built in the concept model. First, when a DPD template is initialized, the system will show the general steps as can be seen in Figure 5-6(a). Then the first step “box1”(shown in Figure 5-6(b)), two instances of module createDPDMolecules are created. These two modules are used to add two molecules, Water and Oil. In the second step View1( Figure 5-7(a)), an instance of module AddDPDMoleucleViewable is created. In this module, only molecules Oil are chosen. So in the simulation window, only modules Oil will be displayed. Then, in the third step, Simulation1 (Figure 5-7(b)), an instance of the module Setbeadsinteractions and an - 44 -
instance of the module setDPDEnvironment is created to set some properties for simulation. Figure 5-7(c) and Figure 5-7(d) show the simulation process. We can see that the molecules Oil will concentrate.
