Description

The modeling method and apparatus for defining the sequence of multidisciplinary analysis and design optimization based on compound component}

The technical field of the present invention is the field of multidisciplinary analysis & design optimization (MDA / MDO) problem definition, and the present invention is MDA / MDO, which is software based on the technology of multi-disciplinary analysis & design optimization. In the framework implementation, the present invention relates to a multi-component analysis and an optimal design method and apparatus based on a composite component that defines a plurality of components and elements as one composite component.

1 is a diagram illustrating an MDA / MDO framework according to the prior art.

Referring to FIG. 1, the MDA / MDO field aims to determine an optimal design while simultaneously considering various engineering analysis fields related to product design, that is, structural analysis, dynamics, thermal fluid flow analysis, control, and electromagnetic field analysis. It is an academic field. The MDA / MDO framework 101 refers to software capable of applying MDA / MDO technology.

Therefore, defining problems based on MDA / MDO technology is to express the dependencies between the software (CAE software) related to various engineering interpretation fields (Computer Aided Engineering) and their respective programs according to various conditions. In addition, it can be linked with CAD (Computer Aided Design) software to support the input and output of the data desired by the user, and finally the connection with the optimization module will be specified.

Computer-aided engineering (CAE) is a computerized numerical analysis or simulation that is used to develop a product. In a broad sense, it means supporting the entire process from product development to design and drafting, but in a narrow sense it is called computer-assisted design (CAD). It means. In other words, it refers to the work of conducting a structural analysis, a stress analysis, a thermal analysis, a vibration analysis, and the like to investigate the strength of the product by simulation. A popular tool for computer-aided engineering (CAE) is NASTRAN (American NASA Structural Analysis System) for structural analysis. The concept of CAE to reduce the number of trials or trials, trial and error, and the development period by using numerical analysis and simulation by finite element method, differential method, boundary element method, etc. was first proposed by the American structural dynamics research firm SDRC in 1980. It became. At present, it is called CAE collectively to examine and analyze various characteristics in various industrial products and parts development such as machinery and electronics by computer.

Problems of Multidisciplinary Analysis & Optimal Design The prior arts in the field of definition can be broadly classified into the following two types.

Procedural definitions

Using elements and components, the process is defined by the user, similar to the flowchart representation.

Dataflow Definition

This is how the user defines the data flow between each component of the process. The scheduler built into the MDA / MDO framework then proceeds as the data changes.

2 is an exemplary diagram of a procedural definition method of multi-discipline analysis and optimal design according to the prior art.

Referring to FIG. 2, the procedural definition method is one of methods for defining multi-discipline analysis & optimal design, and the user can define the procedure in a flowchart form as shown in 201.

The procedural definition method uses component 205 and element 203 to represent the respective problems in a flowchart.

Component refers to CAD software, CAE software, user-defined functions, and software that implements optimization algorithms.

An element refers to elements related to control, among those elements that define multidisciplinary analysis and optimal design problems. RUN or STOP a component, specify a procedure when a specific condition is reached (IF), and repeat several times when a specific condition is reached (DO-WHILE, DO-UNTIL), This is a class of elements, such as the simultaneous execution of components (DO-PARRALEL).

However, when all the procedures are expressed in the flow chart of the problems required by the industry, the following problems occur.

(1) complexity of the procedure

The user can fine-tune the entire processor in a procedurally defined manner. However, as the number of procedures for constructing a problem increases, the processor also becomes very complex, making it difficult to understand the problem throughout the process.

(2) difficulty of reuse

When defining another multidisciplinary optimal design problem, it is often the same or similar to part of the previously designed problem, but it is difficult to reuse.

(3) complexity of the redefinition process

Even the same design problem can make a difference in the execution process depending on the situation. In this case, we will redefine the problem, which is not simple in the traditional way.

In general, multidisciplinary integrated analysis and optimal design problems may then require redefinition with minor changes based on previously defined problems, depending on the requirements at that time. There are many different categories of problems that fall into this redefinition. However, the inventors think that the most frequent thing is to temporarily exclude certain component execution from the entire procedural process in solving the problem.

3 is an exemplary view of a screen for modifying a processor procedure according to the related art.

Referring to FIG. 3, a multidisciplinary integrated analysis problem is largely composed of three procedures, each of which is A, B, and C in the order of execution. Therefore, in order to solve the problem, each procedure must be executed in sequence, such as A → B → C.

In order to execute only the B analysis program as shown in 313 in the procedure A → B → C, the link between the procedures should be broken in sequence as shown in 303, 305, 307, 309, and 311 in the flowchart of 301.

In other words, the process of redefining the procedure for a problem is not simple in the conventional way.

(4) difficulty in concealing information

Defining an integrated analysis & design problem can be an intellectual property of the designer, and if there is internal know-how within the procedures of the defined problem or if there are internal procedures that you wish to cover up to others, do not disclose the details. You should also be able to prevent it. However, in the conventional procedural definition method, such a function is not provided, which makes it difficult to conceal information.

Accordingly, an object of the present invention is to provide a multi-component analysis and multi-component analysis based on a multi-component analysis & optimal design field that defines a plurality of components and elements as one composite component in the MDA / MDO framework implementation. It is to provide an optimal design method and apparatus.

Another object of the present invention is a multi-component integrated multi-discipline that improves the understanding of the procedure of the entire process by grouping procedures that can give meaning among the procedures that constitute the entire problem in the multidisciplinary integrated analysis and optimal design problem. To provide an analysis and optimal design method and apparatus.

Another object of the present invention is to define a plurality of components and elements as a composite component in the MDA / MDO framework implementation, a composite component that can be used to compose a new problem in another field using the already created object To provide a multidisciplinary analysis and optimal design method and apparatus.

Another object of the present invention is to easily redefine the problem by defining a plurality of components and elements as one composite component in the MDA / MDO framework implementation, and whether or not the composite component is included in the overall process It is to provide a multi-component based multidisciplinary analysis and optimal design method and device that can be used.

Another object of the present invention is to define a plurality of components and elements to be concealed in the MDA / MDO framework implementation as a composite component to protect the multi-disciplinary analysis and optimal design procedures reflecting the creativity of the designer It is to provide multi-component analysis and optimal design method and apparatus based on composite component.
