Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a network diagram of the FEM analysis support system according to one embodiment of the present invention. This FEM analysis support system includes a user terminal 10, an analysis control terminal 20, and analysis maker terminals 30, 40, and 50. A network 60 is interposed between the terminals.

The user terminal 10 is a terminal of a user who requests an FEM analysis model and an analysis result, and has a transmission / reception unit 11 for transmitting / receiving information.

The analysis supervising terminal 20 is a terminal that supervises the intermediate processing of information related to FEM analysis, and includes a transmitting / receiving means 21, a searching means 22, a database 23, a dividing means 24, a judging means 25, and an integrating means 26. And The transmission / reception means 21 transmits / receives information to / from the user terminal 10 and the analysis maker terminals 30, 40, 50. The search means 22 searches information in the database 23 based on order information (including order information related to FEM analysis and information related to the user) from the user terminal 10, instantaneously selects an optimal analysis maker, and performs the selected analysis. Get information about the manufacturer. The database 23 has information such as the availability of analysis machines of each analysis maker, technical capabilities (specialty field, etc.), software possession (pre / post / solver), and the like. The dividing unit 24 divides the order information on the FEM analysis in the order information according to the suitability of each analysis maker based on the information on the analysis maker included in the database 23. The judging means 25 judges whether or not the selected analysis maker is one, and also judges whether or not the FEM analysis model is in a divided delivery form. The integration means 26 unifies the data format of the FEM analysis model and performs assembly of the model.

The analysis maker terminals 50, 60, and 70 are terminals of the analysis maker for constructing and analyzing the FEM analysis model in accordance with the order information from the user, and have transmitting / receiving means for transmitting / receiving information.

Next, the operation of the embodiment of the present invention will be described. First, an order will be described with reference to the drawings. FIG.
FIG. 5 is a flowchart for explaining an operation at the time of ordering of the FEM analysis support system according to one embodiment of the present invention.
Order information including order information on the FEM analysis and information on the user is transmitted from the transmitting / receiving means of the user terminal (A1), and received by the transmitting / receiving means of the analysis control terminal via the network (A2).

The order information received by the analysis control terminal is passed to the search means of the analysis control terminal, and based on the order information, the analysis machine vacancy status, technical capability (speciality) of each analysis maker registered in the database in advance. Field, etc.), search for information such as owned software (pre / post / solver) (A3),
An optimal analysis maker is instantaneously selected (A4). Information on the selected analysis maker is passed to the determination means of the analysis control terminal, and it is determined whether there is one selected analysis maker (A5).

In the case where only one analysis maker is selected, the order information is passed to the transmission / reception means together with the information on the analysis maker in the analysis control terminal. The order information is transmitted to the analysis maker terminal to be executed (A6).
The order information transmitted from the analysis control terminal is received by the transmission / reception means of the corresponding analysis maker terminal (A7).

On the other hand, when there are two or more analysis makers selected, the order information is passed from the search means to the dividing means together with the information on each analysis maker, and based on the information on each analysis maker, the ordering information is given to the appropriateness of each analysis maker. At the same time, the order information on the FEM analysis in the order information is divided (A
8). The divided order information related to the FEM analysis is added for each corresponding analysis maker, and is passed to the transmission / reception means of the analysis control terminal. The transmission / reception means responds to each analysis maker terminal based on the information on each analysis maker. The order information including the divided order information regarding the FEM analysis is transmitted (A9). Each order information transmitted from the analysis control terminal is received by the transmission / reception means of the corresponding analysis maker terminal (A10).

Next, delivery will be described with reference to the drawings. FIG. 3 is a flowchart for explaining an operation at the time of delivery of the FEM analysis support system according to one embodiment of the present invention. The analysis maker receives the data, builds and analyzes the FEM analysis model according to the order information from the user, and sends the constructed FEM analysis model and the delivery information including the analysis result from the transmission / reception means of the analysis maker terminal to the analysis control terminal via the network. It is transmitted (B1). The transmitting / receiving means of the analysis control terminal receives the delivery information (B2). Whether the FEM analysis model included in the delivery information is in a divided delivery mode is determined by the determination unit of the analysis control terminal (B3). When it is determined that the delivery form is not a divided delivery form (when the model is completed in one data format), the delivery information is transferred to the user terminal via the network by the transmission / reception means of the analysis control terminal (B4). Delivery information is received by the transmitting / receiving means of the user terminal (B5).

When the analysis control terminal determines that the FEM analysis model in the delivery information has been separately delivered (a model form that cannot be analyzed as it is), the analysis control terminal transmits the FEM analysis model to the integration means having various interfaces. The delivery information is passed once, the data format of the FEM analysis model in the delivery information is unified (B6), and the model is assembled (B7). Assembled FEM
The delivery information including the analysis model is sent to the
Steps A3 to A10 are performed again. That is, the analysis maker is selected by the search means, and the delivery information is divided by the division means in some cases, and transmitted to the corresponding analysis maker terminal from the transmission / reception means. Thereafter, the operation of delivering the delivery information including the FEM analysis model and the analysis result to the user is performed in step B1.
~ B4.

As another embodiment of the invention, the analysis model held by each analysis maker and the required model information are included as information in the database of FIG. 1 and can be converted into a desired data format by the integration means. By utilizing the functions, it can also be used for buying and selling models with each analysis manufacturer as a user.

[0031]

According to the present invention, the optimum analysis maker can be selected instantaneously, and all the processing can be performed through the network, so that the user can obtain the analysis model and the analysis result in a short time.

In the case of creating and analyzing a large-scale model,
If this is left to one company, there was a problem that the analysis period would be longer due to multiple analyses, but this could be split and ordered by multiple analysis manufacturers, so the larger the model, the shorter the time The effect becomes significant.

Further, even in the case of analysis request contents having high confidentiality, there is an advantage that leakage of information to the analysis maker can be prevented. That is, since the whole picture is not transmitted to the analysis maker by performing the split order, there is an effect that the information can be prevented from being leaked to the analysis control terminal.
