Is entered, simulation target data 2 stored in the database 1 associated with the link 10
Is read and displayed on the simulation target screen 3 (window on the display). Then, the result of simulating the simulation target is displayed on the result display screen 7 (window on the display) in a predetermined expression format selected from the keyboard 5 from among preset expression formats.

[Problems to be solved by the invention]

Since the conventional visual simulation apparatus is configured as described above, when a simulation target is read, a temporary reference, a continuous reference, or an associated reference of another simulation target is displayed from a simulation target being displayed. When performing the simulation, the user has to memorize the simulation target and input the necessary simulation target separately from the keyboard every time, which causes problems such as an input error and a reduction in work efficiency.

In addition, when displaying a simulation result, there is a problem that there is only a function of selecting a preset expression format, and a new expression format cannot be added.

The present invention has been made in order to solve the above-mentioned problems, and eliminates input errors, enables efficient access to a simulation target, and adds a new expression format according to a user's request. The purpose is to obtain a simulation device.

[Means for solving the problem]

The visual simulation device according to the present invention comprises:
In order to designate a simulation target to be simulated or referred to, a visual model internally linked to the database is prepared in advance, and by selecting this visual model with a pointing device, the selected visual model is selected from the database. The designated simulation target is read out and displayed by the target creation unit, and a preset expression format is selected by the expression conversion unit, or
A new expression format is added to display the simulation result in an arbitrary expression format according to the user's request.

[Action]

Since the object creating means in the present invention selects a visual model for indicating a simulation object to be simulated or referred to with a pointing device, the user does not need to be aware of (store) the structure of the database or the name of the simulation object. The simulation object stored in the database can be accessed, and the expression conversion means converts the simulation result into a selected existing expression format or a newly added expression format and displays the result. So
Enables multiple result representations according to user requirements.

FIG. 2A shows a case where a simulation target stored in the database 1 in advance before operation is created.

The section 16 and the database visual section 17 constitute the object creating means A.

FIG. 3 is a view showing an object-oriented data structure of a visual model described in the database 1, and shows, for example, a data structure of the visual model. The visual model 14 is composed of a slot name (type name) 22 of data and a value 23 of each slot.

Next, the operation will be described with reference to the flowchart of FIG.

As shown in FIG. 2A, the data to be simulated stored in the database 1 was previously stored in the simulation target creating unit 16 with the icons created by the icon creating unit 15 as the data to be simulated. In the data, first, simulation target screen 3,
Alternatively, the operation is started by selecting the visual model of the database displayed on the visual model display screen 11 with the mouse 6 (step ST1). When the database visual unit 17 reads out the data of the simulation target in the database 1 indicated by the visual model selected by the mouse 6, the simulation target creation unit 16 displays the read simulation target on the simulation target screen 3. (Step ST2), the simulation execution unit 18 and the numerical simulator 19 execute simulation as required (Step ST3). Then, when the simulation is completed, the simulation target creating unit 16 displays a visual model asking whether to refer to another simulation target (step ST4), and allows the user to select the displayed visual model with the mouse 6. If so, the process is repeated from step ST1 again. If not, the simulation target creating unit 16 further displays a visual model asking whether to add a new expression form (step ST5).
Similarly, the user is caused to select with the mouse 6. If it is to be added, the user inputs from the keyboard 5 and defines the function to add the expression form (step ST
6). Then, the expression conversion unit 20 converts the simulation result into an expression format corresponding to the visual model selected by the user with the mouse 6 from among the visual models indicating the selectable expression formats displayed by the simulation target creating unit 16. (Step ST8) The simulation result display section 21 repeats the simulation while displaying the result on the result display screen 7 (Step ST9).

However, a database in a table format created in the main storage device may be used.

Although the result display screen 7, the visual model display screen 11, and the like are windows created on one display screen (each screen corresponds to each window), each screen corresponds to an individual display. May be displayed on the display.
