asic purposes of the concept model. The realization of this model could be described in the following steps. 1) Show the key components in the template to the users when they just initialize the file. As shown in Figure 3-3(a), a structure of DPD simulation is present. The three key steps are “Box”, “Viewer”, and “Simulation”. 2) If the step block is opened, for example, Box, we will see two layers of areas contained in this block. The gray layer is for the default modules. As shown in Figure 3-3 (b), a default module named ‘box’ is shown. So a cubic space is created by the system. 3) Users can put the modules to the area for the new modules. In this instance, only modules which can create molecules are needed here. So only these modules are allowed to this area. Figure 3-3 (c) show a module is created in the blue layer. One hand, when a user opens this step block, the system will only show the proper modules to this step. On the other hand, in case users get a wrong module for some reasons, this wrong module will not be accept by the system. 4) By adding new modules at each step, the program is finished. Figure 3-3 (d) shows the result expected. 3.3.3 Evaluation The advantage of the concept model is that it makes the programming work much easier than both network model and the sequence model especially for novices. This is represented in two points. 1) A novice does not know the general structure of a Culgi simulation program. To develop a program with the Culgi Library in the Culgi GPE or not, he has to learn the necessary steps of a program first. The concept model will show a predefined structure of a simulation program. Thus the novice knows what the necessary components are. 2) The necessary modules are integrated in the component itself. So it improves the efficiency of programming. 3) The logic errors made by users are reduced as the logic is built into the system. However since the structure for a certain type of simulation programs are integrated into the system, this system is not flexible enough to build various simulation programs. For example, in general, users want to see the simulation process, so they need to create a window to display the simulation process. But in the case that a user does not want to see the simulation process, there is no need to create a window. In this case, the original template is not suitable. The solution is that we make it possible for users to create new templates. - 18 -
